This past Tuesday I showed some examples of the GAR (Grand Army of the Republic) insignia inscribed on local tombstones.
The GAR, founded in 1866, was an organization comprised of Union Civil War Veterans. The organization permanently dissolved when the last member died in 1956. Many of the post records did not survive and those that did were given to various archives.
Below is an undated photo of the members of Neptune’s GAR Drury Post No. 372. One of the members is Corporal Simon Peter Young (1840-1912), who served in Company H, 69th Regiment OVI from 1862-1865. Simon Peter Young is seated (on a chair), the 5th man from the left.
Simon Peter Young was married to Elnora “Ellen” (Bush) (1846-1913). They are laid to rest in Elm Grove Cemetery, St. Marys, Ohio.
I prepared a Society of Civil War Families of Ohio lineage application for the family several years ago and they shared these photos with me.
Mercer county had at least four GAR posts at one time, possibly six–the Harold/Harrod McDaniel Post No. 180, Fort Recovery; the McKendree-Murlin Post No. 319, Mendon; the Drury Post No. 372, Neptune; and the Dolph Graves Post No. 429, Shanes Crossing (Rockford).   Stevens indicates that Celina had two posts, the DJ Roop Post No. 61 and the Celina Post No. 710.
