At an antique show in Columbus, OH I found some old family photos from the Willemse family. Most were taken in Amsterdam. The dealer said he bought them from a woman in the Youngstown area who was sick that she had to sell them. They are ID'd as:

Wilhelm Willemse 23
Herman, Dad's brother
Mother Willemse
Father Willemse
Dad, Len and Mom

I see Wilhelm Willemse, his wife Tryntje and son Leonard living in Younstown in 1920 and 1930. I believe Mother and Father Willemse are Wilhelm's parents.
