Annette,
Thank you so much for your help and ideas. I will spend some of this weekend checking them out. I believe Francis was the oldest brother, and I know William was born in 1770/71. John birthdate in County Antrim appears about right. I read in several places that they were from there (Antrim). Is that near County Fermanagh? I believe I have read that the Kenneys, Laws, Burnsides and Sommervilles were from the area of Mcguires Bridge.
Are you corresponding to me from Ireland? Would love to come back there this summer to check records if anything new could be found.

Thanks so much,

Karen
