I did some more digging. His full name was John Peters Ringo, not Ringgold. He was the oldest of five kids. He had one brother and three sisters. His brother Martin Albert Ringo died of tuberculosis when he was 19. He was born in 1854 and died in 1873. He died in Texas but is buried in San Jose California. His sister Fanny Fern Ringo(Jackson)was born in 1857 and died in 1932 in San Jose. Mary Enna Ringo was born in 1860 and died in 1941. Apparently she never married. She is buried in San Jose. Mattie Bell Ringo(Cushing)was born in 1862 and died in 1942. She is buried in Santa Ana California. My guess is since Fanny was the oldest she is the one that received his guns and wallet.
I didn't find any pics of his siblings but I found one of his mother, Mary Ann(Peters)Ringo.
