Have run into a John taylor and mairia in census of Waukesha. Don't Know if this is what you may be looking for?
I am reserching Cheaney of waukesha county, New Berlin and pewaukee TWP's. As for spelling between 1840 and 1900 This branch of family had lots of ways to spell it. I don't have a Maria in this side YET but have found couple loss members in my reserch this could be another. If I could help would be willing.
