The information that I have from the book, "A History of the Beddoe Family" by A.F. Beddoe, A.B, M.D. is that the Eliza Mason Beddoe was born 2/10/1832 in Tennessee the daughter of Philip Tolbert Beddoe & Catherine Parr.She married Cyrus R. Maxon in 1848 in Tennessee.Their daughter Missoura Ellen Maxon was born 7/3/1864 in Tennessee and married William Granville Nowlin on 7/20/1883.Their daughter Myrtle Maud Nowlin was born 3/12/1889 in Smithfield, TX married Earl Otto Tate on 7/5/1908.My information shows that they had 4 children, 2 sons and 2 twin daughters.
Eliza Jane Beddoe was born on 4/25/1846 the daughter of Albert Washington Beddoe and Margaret K Rowlins.Given the dates of the marriage of Cyrus R. Maxon and the birth of most of their children, Eliza Jane Beddoe would have been too young to be the wife of Cyrus R. Maxon.
As far as documents, so far the only ones that I have are copies of the pages of the book that I previously mentioned.
I hope that this helps.Contact me if you would like to share information.
