Romulus and William Wesley Sanders were twin brothers born 2 April 1842 in Indiana (probably in Putnam County).
William Wesley is my 3rd great grandfather. He married Eliza Jane Sanders in Putnam County, Indiana on 20 Aug 1859.
Romulus married Emaline Allen (daughter of Barney Allen) on 11 Dec 1862 in Putnam County, Indiana. Emaline is mentioned in a lawsuit regarding her father, Barney Allen's estate in the Indiana Supreme case of Allen et al vs. Vestal et al on 11 Oct 1867 and it verifies her married name and that Barney was her father.
Both brothers ended up migrating to Missouri from Indiana. They appear living next to one another with their families in the 1876 Missouri state census.
William Wesley settled in McDonald County, Missouri and lived there until his death 9 Mar 1909 and is buried in the Owsley Union Cemetery in Longview, McDonald, Missouri.
Romulus settled in Benton township, Newton County, Missouri. Romulus married his second wife Mary Goodrich Henley on 1 May 1881 in Newton County, Missouri. That is who he is shown with in the 1900 census along with their children. At this time, I have been unable to locate Romulus and his family after the 1900 census.
The bigger mystery for these twin brothers is who their parents were. There are several theories floating around among the Sanders family researchers.
According to some family sources William Wesley and Romulus were adopted by Elizabeth Sanders and their birth surname was Nance.
Another family source says that William Wesley and Romulus were the twin sons of Minerva Sanders, daughter of Wiley and Elizabeth Sanders (this is the Elizabeth they are living with in the 1850 census). The Eliza Jane Sanders who married William Wesley is daughter of Jesse & Axa (Ana) Sanders. Wiley and Jesse are apparently brothers. It has also been reported by this source that after 1850 the twins were under the legal guardianship of an Abraham Lewis (maybe 1852). There is supposedly a will and guardianship papers somewhere that I have yet to see and would very much like to get a copy of which clears up some of this.
