Deb, are you 100% sure that the information you have about Bridget (her parents, birthplace, etc.) is correct? Have you found U.S. records verifying her family? Apologies if you did mention facts in this thread or in your previous off-site threads...
I've not seen any trees as I don't have a sub for Ancestry.
Wow, the first tree is quite interesting. I’ve only glanced at it as I want to have time to check other trees, but this tree has…
John Welch - 1830, Co. Tipperary, Ireland - 1911, Jacksonville, Illinois
Bridget Hennessy - 1838, Tipperary, Ireland - 1908, Jacksonville, Illinois
Daughter, Catherine, born 1861, Jacksonville, IL
Marriage for John and Bridget - 10 November 1862, Jacksonville, IL
Ten more children born to this couple.
The above marriage facts are the same as Deb’s marriage facts. It seems more likely that the marriage for the couple who remained in Illinois would be correct. Again, I’ve only glanced at the tree. On to checking more trees.
ADDED: the owner of the tree either doesn’t know the couple’s parents or didn’t add them to the tree.
