Jerry,
My great-great grandpa William was your Margaret's youngest brother. I show seven children emigrated with one (Mary) age13 dying on the Ticonderoga and one staying in IR (Frances)for sisterhood in Farnham Abby. I have seen your posting re: her letters home during the civil war.
I might also point out that my great uncle Joseph Bohen Breen's [b.1910] family still lives in Fort Smith Ark. and his wife was Marguerite (Black) Breen - I believe the (dr.)Black family remains there also as my father went to visit a few years ago.
I recall my father having a few memories / stories of the Hendricks family.
Thank-You
James W. Breen
