In addition to the two unmarked graves, one grave marker has had the soldier’s name removed, with only the unit, the 10th New York Heavy Artillery, visible. The reason for removal of this soldier’s name remains a mystery. I suspect that the man’s name was misspelled on the stone and relatives had it ground off. After considerable research, we have identified this veteran to be Delos Ervans. Ervans was an active member of Post 250 and served in Company A of the unit that appears on the altered grave marker. Our Camp will be ordering government markers for these three veterans. We will, hopefully, have these stones in place by Memorial Day 1998 and pay a long overdue tribute to these three soldiers.
