I read about this blog post today in the “We are Saving Stories” Daily. It sourced a blog post from Family Search regarding finding the villages of our German ancestors. While those with Dorfprozelten ancestry already know the answer to this question I thought it might be useful to repost the link here for anyone who wants to have a play, or who is still searching: https://www.familysearch.org/blog/german-village-ancestor/
The following useful sites mentioned in the post provide additional information on Dorfprozelten when the name is entered:
Fuzzy Gazetteer http://isodp.hof-university.de/fuzzyg/query/
German Historical Gazetter: http://gov.genealogy.net/search. Within the boxes it gives an option to click on the wiki link and thence to the genealogy forum for the area. Do give it a try.
Geonames search: http://geonames.nga.mil/ggmagaz/. This will give you the village’s coordinates and also map location.
