John McPhail b. 1830 I don't believe that Allen McPhail was the father of John McPhail. Allen married for the first and only time in 1839 to Parthenia. I believe the father of John was the brother of Allen, a John, Sr. b. abt. 1802. He is listed in the 1830 census in Covington County with a wife and one male child under 5. John, Sr.'s wife was unknown. She may have died shortly after the birth of their daughter Mary Jane. John, Sr. died before 1860. The grandmother Dicey raised the last child, Mary Jane, who married John Wesley Dyess.
Richard Dillon Just realized that Richard was my husband's 4th great grandfather, from Clara Morris Milligan. See the Newkirk Family line on Ancestry.com if you have a subscription. Otherwise, we may have to fill in each other's knowledge of similar relatives.
