Does anyone have any info on Earl or Alva Allen, 2 brothers. Both moved to South Dakota around 1907 from Assumption Illinois. Earl married Nettie Cook, Alva married Clara Cook, both sisters. Other sisters were Iris, Allie, Sally, Evelyn, and they had a 1/2 brother Charlie Quackenbush. If anyone has any info on the Cooks, or Allens I would love to know.
