Hi. I've been thinking that Hezekiah Branson Mattison was the brother of my Sarah Ellen since I found them in the same household in 1870, along with P. A. age 22 and Anna age 6. I though the oldest child in this group was Rebecca A., born in 1847. Don't know where she went--or if she and P. A are the same person. Both parents were perhaps dead by 1870. The 1st child of Sarh Ellen Mattison and Samuel Rosamond Kay was born in August 1872. I believe they moved to Texas around 1900.
If I can ever prove that John Mattison was the son of Archibald Mattison and Sarah McAdams, then I would have the connection to John McAdams. The Wakefields of course are the family of Mary Ann Wakefield. Sarah Ellen's mother. It looks like your Hezekiah Branson Mattison and my Sarah Ellen Mattison are indeed brother and sister. Now if we could just prove it!
