Treat Family Genealogy Forum
Sorry, the Treat Family genealogy doesn't include your Abbie -- The only 'Abbie Treat' in the index is Abbie Harriett, b. 15 July 1841 in Frankfort, ME. I also checked all the Abigail's included in the index, but found no one matching the birthdate or marriage info you provided. If you can provide more information (full name, parrent's names, any sibling names), I'll try to check those out and see what I can find.
There are only a few Nichols included in this book, but not John J. There are also several Hall's listed -- give me a name, and I'll try to check it out.
