Hi Judy -
I have that Christian III married Sarah McKenzie in 1815 in Maryland. Perhaps she was a relation of Agnes Mckenzie? They later purchased some land that is near what is now Frostburg, Maryland, and it was known as "McKenzie settlement." I don't know the year she died but she is apparently buried in the Catholic cemetery at Mt. Savage. My uncle got this information from a book entitled "Pioneer Families of Garrett County" by a man named Hoye. He found info dating back to John Henry Garlitz, Christian I's father. I'd be happy to forward to you the rest of what I found in it. - Stephanie
