Emmet A. Summers On your gravesite for Emmet A. Summers: You have his birth year as 1864, and that is what is on his tombstone. He was, however, born on 12 May 1868. That is the date given on a social security record. The 1900 census states May 1868. Other census records list his birth as 1868. I have a hunch someone made an error on the stone. You can change it if you want to.
