One of my fellow researchers places Frank (Francis or Franciscus) as a brother to my ancestor, Joseph Mlodzik, who settled in Princeton, Green Lake Co. WI. I have no proof of this, and I think that obituaries may give us more information, though the ones I do have don't name brothers or sisters. My information on my ancestors' births came from LDS Family History film # 585811. Frank married Josephine Thomas or Thomes, and there was another Joseph Mlodzik who also immigrated to Minnesota (Duluth), who was married to a Florence Thomas, which makes me think those 2 families might be related. It's possible that Frank and Joseph may be cousins to my ancestors.
