I am looking for information on my family line of Charles Edwin Derby b. 1884 and Mary Amy Doherty b. 1891. They were both born in Iowa, unknown place,and ended up in Hartington, NE. They had 16 children and many descents still live in NW Iowa. Any help on this line is greatly appreciated. Any help on the brothers or sisters of my grandfather, Charles Edwin Derby, would be appreciated. Thanks and May God Bless.
