Hi Paul- Thanks for all of the information. I never meant that David was “the” oldest Alleman ancestor—just the first to enter my family tree by marrying into the Urdahls.Because that side of my family (my father’s side) is almost exclusively Norwegian, I took a guess at the origin of the Alleman name.
Inger Urdahl was my great aunt.Her mother, Mari Gundersdatter Rugtveit, had a child out of wedlock while she was still living in Norway.That child, Martha Serena Urdahl, was my great grandmother and Inger's half sister.
Martha married Tom Arendts, who was also born in Norway.They lived in Story County for a while, but settled in Kensett in Worth County.One of their daughters, Mary Anna, married my grandfather, Orin Knutson.They raised their family in Kensett, but eventually moved to Polk County--specifically Des Moines.
I spent a lot of time in Des Moines, Story County, and Worth County while I was growing up. Who knows--we might have bumped into each other a time or two. :)The Sheldahls, for whom the town of Sheldahl in Story County was named, were also members of my family.As a matter of fact, a cousin Caroline Sheldahl married Peter Ahlman in the early 1900’s.I always wondered if this name was related to your Allemans.
