Did you happen to find this site while searching for your Byrne ancestors? I’m glad you visited, but want to warn you up front there are very few Byrnes on ByrneFamily.net. In fact, of the 18,000+ genealogical records on the site, fewer than 100 are Byrnes.
The reason for the dearth of Byrnes on the site is that my line descends from an early American, John Byrne, born in Windham Connecticut in 1760. Efforts at tracing this Byrne line back to Ireland or otherwise have been fruitless to date. And there’s a wrinkle to the story in that John Byrne may not have been a Byrne at all. Genealogical DNA evidence shows the John Byrne line (or possibly his son, George) actually descend from lines tied to the Cole surname, and it’s likely that at some point in 18th century Connecticut a child fathered by a Cole was given the name Byrne.
So where to go if you’re looking for a comprehensive database of Byrnes? Aside from the usual spots (e.g. Ancestry.com, Familysearch.org, etc.), Paul Burns has been leading an effort document and publish multiple Byrne/Byrnes/Burn lines via the Byrne DNA project. While not an uncommon name (Byrne is not even in the top 1000 surnames in the US), it’s extremely popular in Ireland, ranking 7th in popularity, and you’d be well served to check in with the Byrne Clan, which focuses on Irish Byrne descendants.
If you did happen across the site in search of info on John Byrne’s lines, or for that matter some of the other larger branches (Barteau, Rue, Trapnell, Garland, Cosby, etc.), please say hello. Both myself, and Wayne Garland, who manages the Garland data on the site, are always interested in sharing information with other family researchers. And for those on the hunt for other Byrnes, best of luck in your search.
