Jack has written and improved ten profiles for the Biography Builders Challenge.

Descendant of Robert Harrington of Watertown



I've been a WikiTree member since February 3, 2013. I'm a member of a number of Projects which reflect my interests--feel free to contact me in connection with any of them!

Major Roles in Major Projects

Team Leader

I'm Team Leader for the Province of Maryland Team of the Southern ColoniesProject and welcome new team members.

Project Coordinator

  1. Disproven Existence Project I'm Project Coordinator and resident early medieval/pre-medieval expert as well as Maryland liaison. I coordinate efforts to evaluate simple Disproven profiles (with the research box) or Uncertain profiles/groups and the various steps to get them added to the project (or by another interested project).
  2. Euroaristo I'm Project Coordinator for the Ancient Royals subproject covering profiles of persons born prior to 742. I'm working with John Atkinson, the project Leader, to find ways we can add manpower to developing these very early profiles.
  3. Maryland Project. As Project Coordinator I lead this subproject of the United States Project. I have been working on my Maryland roots for many decades and maintain a significant personal library of Maryland resources
  4. Indonesia. Having spent part of my growing up years in Indonesia, I founded this project which is now a full-fledged project with a Leader. As Project Coordinator I help volunteers with bilingual and trilingual profiles and categorization.

Minor Roles or Minor Projects

  1. Ranger Project. As a member of the "Saturday Shamrock" team I take my public service turn helping monitor potential harm to our site.
  2. Categorization Project. As a former Project Coordinator for this project, I continue to be liaison for the other projects I'm involved in.
  3. Magna Carta Project. I highly value the rigor of the Magna Carta project which has affected everything I do on WikiTree. I appreciate the chance to document early English nobility. As a former Project Coordinator and emeritus member of this project, I hope to find time to do another Magna Carta trail some time in the future.
  4. England Project I help with very early profiles and have a special interest in Marcher counties like Shropshire and Cheshire because of their proximity to Wales. This also makes me part of the United Kingdom Project
  5. Early Scandinavia Project I joined this project because of ancestors in extraterritorial Scandinavian entities like the Kingdom of Dublin
  6. Asia Project. I helped found this minor project at present which does not have a Leader, but hopes to become an umbrella project related to various Asia Projects such as Indonesia and India.
  7. Profile Improvement Project I joined the Profile Improvement Project because of my interest in well researched profiles.
  8. King Arthur Legends Project I helped found this small project which engages others in linking together real and legendary people associated with King Arthur.
  9. One Place Studies. I really haven't done anything with this, but I have a particular interest in Llangollen, Wales and Damascus, Maryland.
  10. Wales I work extensively with profiles of pre-1500 Welsh nobility.

Personal Projects

  1. Sampson Waring Ancestors Project. I've created a "personal project" for this that others are welcome to join: Sampson Waring Ancestors Project (August 15, 2018). This project traces the ancestry of Sampson Waring, born in Shrewsbury in 1616, back to his possible Norman and extensive Welsh nobility roots. (So far, nobody has!)
  2. I am tracking my own other ancestral lines at Space: Jack Day's Ahnentafels.

Genealogy Publications

  • The Story of the Maryland Walker Family, 1957 (15 pages, mimeographed). Produced when I was 15 years old, and I was thrilled when the Library of Congress, New York Public Library, and Montgomery County (Maryland) Historical Society accepted copies of it for their collections.
  • James Day of Browningsville and His Descendants: A Maryland Family. Columbia, Maryland, 1976. Softcover. Out of print, but several hundred copies in circulation. Over 2000 descendants of James Day, my great-great grandfather who guarded British prisoners of war in Frederick, Maryland during the American Revolution.
  • Three Sisters Went West: An Essay. Looking at the human story behind the dry facts.

Available Databases

As a lifelong genealogist, I've developed "databases" of a pre-1800 information on a number of Maryland families. These databases are in MS Word files. They arrange bits and groups of bits of information according to the actual or guessed birth date of an individual, so that contemporaries are grouped together. There are footnotes giving source wherever possible. These databases aren't perfect, of course, but they often contain more information than one can find elsewhere in one place. I'm glad to share these databases with anyone who agrees not to post them intact on the internet -- they contain some coding (such as G in front of a date to indicate it's an educated guess) that would not make sense out of context! But I'd be delighted if anything I've done contributes to enhancing the profiles you work on for WikiTree. So just send me a note! Here are the family names for which I have databases. The focus is on Maryland families before 1800.




My father's family came from upper Montgomery County, Maryland, and many trace back to colonial Maryland. My mother's family came from upper New York State and trace back to New England. My sister is a member of the DAR and other lineage societies. I have joined First Families of Maryland.

Cousins on WikiTree

I've re-arranged the list of my cousins on WikiTree in order of their closeness!

  • Dennis Barton is my fourth cousin, with Peter Beyer, born 1760 in the Duchy of Wurttemburg, Holy Roman Empire, as our common ancestor. Peter Beyer migrated to Browningsville, Maryland, where the farm he started is still owned by his Walker descendants.
  • Andrea Greene, born 1970's, is my 4th cousin, once removed, Our common ancestor is Joshua Purdum, born in Montgomery County, Maryland, 1767.

  • Paige Sgrignoli is my nineteenth cousin, twice removed, with Walter Bromley, born 1320 in Cheshire, England, as our common ancestor! Later on 10 January 2020, Paige is now my 20th cousin once removed, with William Bromley, born 1320 in Cheshire, England, as the common ancestor.

Jack, thank you for intervening in the Lee-3470 matter. I thought my role had been to merge an empty Lee-27963 into Lee-3470. When I process a merger request, I always try to determine that the persons match up, and that the life facts line up. With these profiles, only the 1678 death date was off on Lee-27963, and it was before some of the known children were born, so I accepted the 1736 death date on Lee-3470. I did not add the family tree to the profile. I only moved the reference to it into the Sources section. I am skeptical of unsourced family trees and never rely on any from However, as part of a GEDCOM cleanup in a merger, I will list all sources, including family trees, as a courtesy to past contributors, if a suitable substitute has not been offered, and I do search for other sources to validate the story related in profile.

I offer my assistance if needed. David

Thanks, David. I'm trying to ascertain now if I can find any additional information on the various Thomases and their Elizabeths, which will determine how to proceed! If you think of it, come back to these profiles in a month or two and see if whatever I've done actually makes sense!

Hi again Jack, from a 20th cousin,

I just have a question about Henry Longe. I see from the Changes page that you changed the status of his parents to Uncertain. Is he still a "Sir"? If not, could you or James Allen kindly remove that prefix? It's a little confusing.

Thanks cousin, dusty

Dusty, I think I changed the parent status to uncertain because there are no reliable sources for that information , and parent status is a key thing people are interested in with respect to their genealogies/family trees. As for the "Sir", that's reported in some of the same sources, but it didn't seem to be that important. He could have been Sir by heredity or by being specifically honored. The key thing for the profile is to find more reliable information; then such questions go away.

Hello Jack, I'm not on WikiTree often so I just saw a comment you left for me re: Mary (Beall) McPherson. I have spent a lot of time in Sinking Creek, VA. talking to "cousins" and folks that are familiar with our McPherson/Beall ancestors and of course I enjoyed our "Gathering" we had in May 2019 when we placed a monument to both Alexander and Mary. It was a wonderful event.

I would be interested in learning about and participating in your Beall research if you are interested. (FYI Mary Beall McPherson was my 5th ggm).

Hi Jack,

On Collineau de Montaguerre, you left a note about her mega-spouses. She is found as ancestress for oodles of French immigrants to New France on certain trees on the net, none sourced. There are multiple G2G discussions linked to the profile that explain how her existence was disproven. Not much more can be done. The purported spouses are all tagged with uncertain existence and categorized with the appropriate categories. No children are linked. The spouses remain linked to show just how wildly improbable she is.

Hi Jack,

On behalf of the England Leaders, I wanted to say a huge thank you for all your contributions towards the project in the past six months as a Team Member for Sourcerers, Shropshire and Pre-1500 Prep. We've achieved a great deal during this time and we couldn't have done it without you.

Are you happy to stay in your current teams and the project as a whole? Are there any other teams you'd like to join? What are we doing well, and what would you like to see us doing differently moving forwards?

Please respond to this message via e-mail. I look forward to hearing from you.

Many thanks,

Susie, England Project Leader :-)

Hello, Jack, you asked about the Emison book on the Gassaway/Shipley lines, and the source attached to profiles listed FHL digitized microfilm version, so I attached the appropriate URL link for viewing. The other Gassaway book by the Rutherfords, several years ago the link was digitized and the book was viewable, but when at the FHL centers. Thanks for your message, Jack.

Hi Jack this is Nicole from Alexander McPherson's profile page you left a message there for Richard and I haven't spoken with him to see if he received it, but I know I can speak for him saying that was are both very interested in working with you concerning Mary's parentage and Beall's in general! Thank you

Hello Jack. Thank you for your interest in the DEAN family. I certainly grant your request for trusted access to Lydia Dean. ( Many years ago I received a message to the effect that "Lydia Dean was dau. of Thomas Dean, who was brother to Hannah Dean, mother of Thomas Morey's first wife, Mehetable Hodges." This was ferreted out of a series of land sales by George Hall, after 1726. He was appointed guardian of his children, who as minors, inherited large tracts of land (being a portion of the Taunton North purchase), lying in Norton, then Easton, from their grandmother, Katharine Dean, and aunt, Hannah Dean. In trying to go forward with this information I was unable to sort out the descents and relationships of/ between Thomas Dean & Hannah Dean because Hannah Dean has a different parent here on WikiTree than Thomas Dean.
