This thread doesn't really tell much about your Utecht ancestors, but there were at least 2 Utecht families that used Milwaukee's German language newspapers for their family notices: Herm. & Carolina, and a Wm. and Mathilda. This info. comes from the library resource called "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950). The Utech / Uttech spellings are more commonly found in these papers with over 100 entries or references, but there are about 25 Utecht / Uttecht entries or references - even Utteck (Geo. & Olga).
