Tough to tell. My father (WWH IV) was born in Wisconsin in 1917. His father(WWH III) would have been 20-40 years older. He met my Grandmother (Elyse Schwenkee)on the ship coming to America. My dad was their only child, so I imagine it couldn't have been much before that that they were married. The story was that he left IOM and traveled to Wales, where he caught the ship for America.
