Many thanks to Linda Heneghen for her contribution to this study.
James M Cumpston was born in Pennsylavania around 1835. He was married to Elizabeth Thomas.
They had one daughter, Julia Ann (Linda's great grandmother).
He was in Co. E. 15th regiment of the Kansas Voluntary Calvary. He lived in Texas most of his life after the calvary, but he had left the family when Julia was little.
Linda has his calvary records from the National Archives, but at present has no knowledge of his parents or siblings or any other family member.
