was really surprised about your message since I had not expected anyone to respond that much later, actually had nearly forgotten about it.
Interesting however to read how the surname's spelling has been changed from Wippel to Whipple ... I was suspicious of that, but was not sure.
I do not kow Roxheim, but Koblenz area is familiar and not too far from where I live now. Actually, it is close to France, and there is some rumor my father's family may have comme from France.
I will take a closer look at that !!!
Thanks for your info, and will keep you updated in case I find anything of interest!
