I have been gathering information on my family for about 20 years. I have researched both my own family and my late wife's family. I started with an extensive file of data that was collected by my grandmother in the old fashioned way before the internet had been invented. I inherited a large box of data from her and entered it into my ancestry file using Family Tree Maker. Around 1980, my nephew recorded interviews with my parents for a high-school project. He has sent copies of the audio tapes to me and they have provided much information to me about my parents' early life.[1]

I have greatly enlarged my grandmother's data using the resources available on the internet and my own personal knowledge.

About two years ago I began using Wikitree and uploaded my Gedcom file from Family Tree Maker, which contained about 2000 names. Since then I have been trying to edit and clean up the resulting profiles, as well as adding to my tree through matches and merges and additional research. I have created the Chadwick Name Study page and have taken the FTDNA yDNA-111, mtDNA and auDNA tests to aid in locating other relationships.

Using mostly my grandmother's data, I have traced my direct paternal ancestry back to John Chadwick, who immigrated from Rochdale, England to Watertown. MA. John is my 7th great grandfather. He lived in Malden, MA and married Joan Shepard in Massachusetts. Of my four grandparents, three can be traced back to England and one to Ireland.

My grandmother was named Edith Clark Chadwick and she lived in Massachusetts all of her life. She left behind several scrapbooks into which she had pasted her typewritten genealogical notes on the Chadwick family, the Clark family and their numerous branches. I have copied one of these scrapbooks into Chadwick Genealogy Album

I have been able to identify 24 of my 32 3rd great grandparents. The remaining eight are the ancestors of my great grandparents who came to America from Ireland in the mid-nineteenth century. Their names were John Dunsworth Barrette and Margaret Maebanks. I have been unable to extend this branch of my tree any further and consider this to be a "brick wall".

My wife, Sheila's, ancestry has been much harder to trace. She is descended from immigrants from Czernowitz, Austria-Hungary (now Chernivtsi, Ukraine) on her mother's side and from Gaisin, Ukraine on her father's side. This is another brick wall.


I was born in Louisville, KY on 21 Nov. 1937.[2] My father was an Army officer who was stationed at the time at Fort Knox, KY. I was the last of four children. Before me were three sisters, the youngest of whom was more than eight years older than me. When I was about 18 months old, the family moved to Oahu, Hawaii.[3][4] In 1941, my father was stationed at Hickham Field, adjacent to the Navy base at Pearl Harbor and I had the experience of living through the Japanese attack on December 7. My mother, my sisters and I were shipped back to the mainland as military dependents, My father went on to join the 25th Division and be sent to Guadalcanal, See Maurice Chadwick. The rest of the family moved to my paternal grandparent's house in Waltham, MA and then to a house in Dedham, MA until my father returned in 1943.

After that I lived as a child in Washington, DC, Fort Monmouth, NJ, Ithaca, NY, Tokyo, Japan and Weston, CT, where my father retired from the Army and started work as a civilian. I went to public school in Weston, high school in nearby Westport and to college at MIT, getting a BS in Electrical Engineering. I started work at Norden Division of United Aircraft in 1960 and worked there until 1965 obtaining an MS part-time at Yale University. In 1964 I started doctoral work at New York University.

In 1965, I met my wife-to-be and also left work to become a full-time Ph D student. Sheila Brass and I were married on my 28th birthday in 1965. In 1967 I finished my Ph D and we moved to Pasadena, CA where I began to work at the Jet Propulsion Laboratory. In 1973 we moved to Reston, VA and have lived in this area ever since. My children have grown up in Virginia and have moved on to live their own lives. Sheila, my wife of 47 years, died in 2012, but I still live in the same house in Herndon that we bought in 1989. I retired from IBM in 2004, after working there nearly 30 years.[5]

DNA Notes

The following is from Alex Williamson:

ZZ10 is on one of the two arms of the P5 palindrome, but as of right now it is anyone's guess as to which arm it is on. ZZ10_1 refers to the possible position on the arm closest to the centromere, and ZZ10_2 refers to the same position on the opposite side. Because the regions around those positions are so similar, NGS or Sanger sequence tests can't tell them apart. All your FTDNA results are indicating is that it could be on either arm, that's why you see both ZZ10_1+ and ZZ10_2+.

Mayflower Project Member.

I see your profile doesn’t include a mayflower G2G Tag. See “Followed Tags” above. You should have the tag - mayflower -so you can follow pertinent Mayflower activities on G2G. When you add the tag, please include the names of passengers in whom you are interested. Thank you

Hi Henry,

I hope all is well with you. I've not yet heard back from you about which team(s) you would like to be on in Global Cemeteries. If I don't hear back from you in the next week I'll assume you'd like to withdraw from the project for now.
