Isaac WALLEN born abt. 1818 came to Jennings Twp., Putnam Cty., Ohio abt. 1823 with his parents, Elias and Ann MARTIN WALLEN. He married Catherine Nordhoff, born in Germany. Her parents moved to Jennings Twp.. Mrs WALLEN'S mother was also called Catherine NORDHOFF. I am looking for information regarding the elder Catherine's other children. Frank WALLEN was listed in the US Census as living with her. Frank WALLEN married Katherine SCHLOTTMANN/SLOTMAN. They had a large family. Any information regarding the descendents of this large family would be most helpful. Thank you. Beverly WALLEN.
