I've recently been in touch with Patrick who replied to you earlier. It appears that we are related through DNA. My Schmidt/Smiths lived in Frederick County, MD. My ancestor was born about 1745-1755 in Alsace. They spoke German and were Lutheran. I am looking for his parents and siblings.
Patrick's John Smith was listed as Johannes Schmidt in church records in Page County.
I was born in Luray and am also a Griffith descendant. I find it so bazaar that a Schmidt relation lived there too when mine were in Maryland. Hopefully we can find the connection.
