I have not been in contact with the two persons you mention. Would you be so kind as to e-mail me at email@example.com
with their contact information. I found on www.findagrave.com
that there is a notation that John Hannah was a Revolutionary War Veteran, but his birthdate was 20 years after the war. I believe if there was a Rev. War Veteran marker near John and his wife Summerfield it may ahve been for John Anderson. I would like to get a government marker for John and have it installed in Calrk Cemetery if I can verify the Rev. War marker mentioned.
