Hi. I have just started working on my Ehlert family line again. I have good news for you! My Great-grandfather, Max Frederick Ehlert was Lily Ehlert's brother! My information shows that Lily and Chris E. Sievers had a daughter,Ruby who married Gerhart Knop in Council Bluffs;and a daughter, Lois Sievers,born in 1920, who married Maurice W. Render on 22 Jan. 1946. If this is your family please contact me. I have some photos of Lily and her siblings, their parents, some newspaper clippings, obits, and am working on their connection to Germany and possibly Russia where Lily's parents are from.
