Pat.....I guess Emma & Leucha would be the same person. I'm still trying to find Elsie's parents after 1870. I have no idea where or when they died. I ran across Kriene in the 1880 Ackley, Hardin County, Iowa census. His name was misspelled as Kasjins.

Kriene and Lina both gave their place of birth as Hannover. I did look to see if there was a Hannover in Ostfriesland, Germany. I did find one. The first two children were born in Illinois and the other two in Iowa. That would put them leaving Illinois after 1874.
