i have been looking into some names in the portage county, wisconsin area, my grandparents were from that area.one of the names i have information on is wanta. some of the information is from ancestry.com, either the census records or wisconsin marriages. Josephine SZTYNKA and Joseph WANTA, married 24 nov 1885, Portage County, Wisconsin (Record 01 page 0478) have not noticed anything is the census records yet.
also, information from "Stevens Point Area Obituary" (this is online) Obituary: WANTA, Joseph Mrs., STANKE, Josephine-Stevens Point Daily Journal27 May 1946
there are 7 Joseph WANTA listed, all died before 1975, i don't know if he is one your looking for.
Stevens Point also has a cemetery locator that list names of persons buried at cemeteries located in Portage. only the one's with gravestones, Josephine is not on that list.
if that is the Josephine you are looking for you might want to get a copy of the obit, it might give you some informationthat would be helpful to you.also, note that the spelling of any surname can be different depending on who and when it was written. some seem to be done by sound.
try looking into Portage County message board, or if they lived in a different county, marathon is right next to it.
try ancestry.com for wanta, you might find information from the message boards.
