Marie Jelsma their may have been more than one, I don't remember but my Aunt may have named her daughter Marie? I don't recall meeting them in CA. I was 5 yrs. old when we visited her.
Jelsma is from the north part in Holland and they are the Friesland tribe. De Young's were from Amsterdam and my grandmother was related to the Queen Wilhemina for she was a De young.
