Thank you for your reply.Please see my posting of information on related family info on the Thorp (no "e")forum #826. I contacted SAR and was in turn contacted by Mr. Burkland of the Michigan Society of the SAR (missar.org). He was as perplexed as I am because there is no record of an Ebenezer Thorp on pension lists etc. He was the one who posted the picture of the marker on the SAR website and he said he'd look into it when he can. He thought part of the confusion on my part could be that this was Ebenezer's second family. I was thinking along the same lines.
I agree with you that an "In Memory" marker is not always a gravesite. However, I can find no other gravesite for him and since his wife is buried in the same cemetery . . .
Anyway, I live no where near Michigan and have not contacted the cemetery yet.Do you live there?I would of course appreciate any help you can give me. Please email me.
