Adding a Profile to this Study

Please avoid adding every Longan profile to this Study. See List of Longan Profiles below, to get a sorted list of every Longan profile on WikiTree.

The criteria for adding a Longan profile to the study are:

  1. Add a Longan profile to this study if their Longan ancestor is currently unknown.
  2. Add a Longan profile to this study if they are Adopted. See the "Adopted" section below for more information.
  3. The top level progenitors of the main Longan families have already been added to the study.

To add your ancestor to this study, simply copy the following template to the Biography section of his or her profile:

{{One Name Study|name=Longan|category=Longan Name Study}}

Once the profile is connected to the main Longan family line, then remove the template from the profile.


  1. Take existing Longan profiles on WikiTree, and use records found on FamilySearch.org, and Find A Grave, to reconstruct pedigree as much as possible
  2. Find other Longans on FamilySearch.org and Find A Grave, add them to WikiTree, reconstruct pedigree or find where they fit in existing families
  3. Find any historical newspaper references to any Longan in the United States
  4. Find any histories of the Longan family, whether books, previous personal research, or other written materials. Use these to compare against primary records.

Longan Genealogy

The Longan surname seems to be Irish in origin. It is likely similar to the surname "Langan", which some research has shown that it too is Irish in origin, and likely pronounced the same way. More research needs to be done to determine if "Longan" is a spelling variant when families immigrated to America.


There is a primary Longan family in the United States, with (currently) one other family that immigrated separately.

The progenitor of the primary Longan family in the United States is supposedly Thomas Longan (1670 - 1740). Currently we don't have sources to prove his existence, but he was supposedly born in Ireland and died in Virginia.

Thomas supposedly had a son, Augustine K. Longan (1710 - 1774). Again, we currently do not have sources to prove his existence, but he was supposedly born in Virginia, and died in Virginia. It is interesting to note the name 'Augustine' is a recurring name in the Longan family.

Augustine supposedly had two sons, Patrick Henry Longan (1742 - 1804), and Edmund D. Longan (1772 - 1849).

Patrick Henry Longan, and his descendants, seem to be well documented, as he served in the Revolutionary War. The majority of the Longan family in the United States can be traced to Patrick Henry Longan.

Edmund D. Longan is not well documented, but he has descendants that are documented. If Edmund D. Longan is a brother of Patrick Henry Longan, then it is interesting to note that they were born essentially 30 years apart. This calls into question if they are actually siblings, and who Edmund's parents actually are. This needs more research. Perhaps the best way to determine if descendants of Edmund D. Longan and Patrick Henry Longan are related is through a DNA test.

Research has uncovered another Longan immigrant from Ireland, John Longan. This person is also unsourced, but has descendants.

Intermarriage with the Bowles Family, Knight, and Weber

There are at least 4 marriages with the Bowles family, including two wives, who are Bowles, early in the Longan genealogy:

The name "Bowles" shows up as a middle name repeatedly in the Longan family. We don't yet know the full pedigree of Mary Elizabeth Bowles, Mary Weber Bowles, John Bowles, nor Edward Bruce Bowles. However, there is a prominent, and prolific, Bowles family in Virginia, that goes back a long way. Edward Bruce Bowles is said to descend from Bowles in Virginia. Interestingly, one such family is John Bowles who married Sarah Knight, probably in the early 1700s. The name "Knight" shows up in the Longan family and is repeatedly passed down among family members. Could there be a connection to this John Bowles and Sarah Knight? The name Knight also shows up in the Bowles family as well. At one point the last name "Webber" or "Weber" also shows up in the Bowles family. Much research is needed to connect all of these lines together.
