Richard Riker (1834-1853)
Died in early adulthood, almost certainly unmarried
He was named as the late father of Margaret Moore Riker at the time of her marriage in 1914. However, seeing as Margaret had two siblings (Samuel and Ruth) and their supposed father was just 19 years old when he died, this seems unlikely. Also, Margaret was born in 1889, 36-years after Richard died.
