The LDS have the Lutheran Parish's of Neusatz, Zuerichtal and Simferopol all filmed from 1833-1885. You should find what you need in the Simferopol Parish. But I would check the other two out also just to make sure.
Also there is Upton mentioned on the Odessa Pixel site http://www.odessa3.org/search.htmlhttp://www.odessa3.org/search.html. There is not that many Upton's shown but your William. In the Query Strin type in the surname and in the Data Category click on the RH side on the little arrow. There is 13 different things to check out.
