I am searching for my maternal grgrandfather,William Hemphill Johnston or possibly his given name was Joseph William.Sources report that in 1869,grgrand.was married to Emmaline Nix,and living in San Marcos (Hays County)Texas.In 1872,Emmaline died after giving birth to twins (one of whom was my maternal grandfather(Andrew Hemphill Johnston).After Emmaline's death,Andrew and siblings were brought to Texarkana (Bowie County ) Texas where they were raised by Emmaline's sister Caldonia "Callie" Nix (about to be married to Big Will Russell.I do not know what became of grgrandfather,nor do I know where Emmaline was buried after her death in 1872.My Grandfather ,(Andrew Hemphill Johnston)died in 1936 in Texarkana and is buried in the Northwood Chapel Cemetery in Pleasant Grove (Bowie County)Tx.Emmaline was believed to have been born in S.C.in circa 1844 and may have a given name of Martha,i.e.I am not certain that Emmaline was her first or given name.Nothing in Hays County records that I can find give any clues as to what became of Grgrandfather or where grgrandmother was buried.Grandfather married Martha Emma Shipp.any help would be appreciated in solving the mystery.Thanks.
