My paternal great grandparents were Ignatz & Elizabeth (Lowiec) Len of Lake County, Gary, IN. Supposedly, Ignatz had a brother Lawrence & a sister Frances. This is according to an account given to my mother by my Grandmother (Rose Len) about 45 years ago. They all were Polish/Austrian, depending on war lines of the era. Sorry I don't know more, and I don't know if this is helpful at all.
