I think Benjamin Roach may have been born in 1852 TN.The family believes that he was a physician.There's a family legend that he was kidnapped, taken blindfolded and forced to treat Jesse James who had been shot.I can't find any verification of this.
Ben married Jessie Jones (Abner's daughter) on 24 Apr 1893 in Medina, TX.Ben and Jessie had 6 children that I know of: Kyle, John, Benjamin, Nita, Abbie, and Elsie.
He was married previously, but I do not know his 1st wife's name.They had 2 children: Lavelle and Horace.
The family legends are that Abner immigrated from Wales.He was born about 1850.(note that he was only 2 years older than his son-in-law, Ben.
