Thank you, John, for the information on Trimmers in England. I have no known links to these Trimmers. So far my only links are to Johannes Trimmer in Neuwied, Rheinland-Pfalz.
A professor of German recently explained that the "ü" in the name Trümmer can be replaced with an "i", giving us Trimmer. So the names Trimmer and Trümmer are the same name. This might be a lead in helping trace Trimmer origins.
