My ancestors emmigrated somewhere around 1536 from Swiss Canton Thurgau to America (Utah). I was researching a lot and there are lots of black holes about them, but i've found a brother of my grand grand grand... father, called John Urech, who lived around 1790 somewhere near Milwaukee. Could he correspond in any way to your John Urich? My grand grand grand... father was called Fred. He or his son emmigrated back in 1796-1798 to Switzerland (Schaffhausen). I think that the Urech's either speak their name Urek, Uric or Urich in english and Uresch in french.
