I'm totally blown away! I have a picture of Christian Louis on my tree!! Your grandfather and Ida are on there too, but without pictures. I've met a couple of other von Mehren descendants through Ancestry, one from the U.K. and one from the U.S. Send me an e-mail and we'll talk. I'd love to exchange information with you! My e-mail address is firstname.lastname@example.org
. I'm so looking forward to hearing from you.
