My great-great grandparents, Fred Will and Katherine (Juska) immigrated to Sharon, PA in 1905, one year after being married. Church records from Neu Pasua, the town on the Danube River that they the came from, list their last name as "Will." On US censuses its been listed as Vill, Well, Will, and Wills.
They had chidren: Katie, Fred, Frank and Elizabeth. Fred went by the last name "Wills." I do not know about the other children
Their next door neighbors in Sharon, who were related to them, were Matau and Anna.
Fred's parents were Michael and Elisa (Flohr). Michael's parents were Michael and Elisabetha (Popp). Michael and Elisabetha also had two daughters - Magdalena and Margaretha.
It is believed the Will family is part of the influx of German settles to Neu Pasua around 1790, but I've yet to verify that.
I do have two pages scanned frm a book on Neu Pasua births/marriages that are in relation to this family. I'm willing to share those pages with anyone who asks
