I may have a connection. I am a descendent of a Teunis Roelof Klein, who immigrated in that timeframe to Pella, Iowa.
My Teunis was born 26 November, 1876, and died in 1953. He married a Charlotte Bruinekool, and they had four children. One of them was another Teunis, my beloved grandfather.
I would love any information you might have as to where in the netherlands they were from, and if my Teunis might match yours. He was reportedly quite a pistol, a fairly stoic man who used to put the rings in his bulls' noses with a quick stroke of his pen-knife. Lottie, his wife, was pregnant out of wedlock with another man's child when he married her - scandalous!
