From your note I cannot determine either the cemetery or the individuals you are talking about. I have shot in several hundred cemeteries in about 7 different states. Give me a little more help here and I will tell you all I know - which might not be that much. What cemetery are you referring to and what individuals are you interested in?
RE: Floral Park Cemetery They are probably next to each other. I can't tell you definitively. I am basing on the way I take pictures and add them to FindAGrave. The memorial numbers are very close so it tells me I didn't take any pictures between them.
RE: Private Dooling I have shot nearly all of NY, Mass, Ohio, Ind, WV, and a great deal of PA. I have not done many of the US soldiers in the central part of the cemetery. The safest bet is to go to the Find A Grave site for Antietam, bring up alllisted graves & then click on the thing saying graves without photos. Gather a bunch of those names N have a good day hunting.
"John left Liverpool England and immigrated to the United States arriving in New York on 25 September 1835 on the ship Bark Cyrus Butler. The rest of the Uzzle's immigrated to the United States in 1843 from Wales to Pottersdale, Karthaus Twp, Clearfield County, where he obtained employment at the furnace. John is buried in Bridgen's Cemetery (The Old Oak Hill Cemetery) in Karthaus Township, Clearfield Co. PA. In 1870 Joannah was living with Son-in-Law Christian Graham and Daughter Anna in Iowa."
I'll have to dig out the source info. It was back in the days when I didn't appreciate the importance of notating everything.
John was my third great grandfather and Christian and Anna my 2nd great grandparents.
