I'm a professional librarian and archivist, and a hobby genealogist, always searching for the full story on my Simmons (Georgia), Leonard (S.C. and Maine), Hazelden (S.C.) and Smith (S.C.) ancestors.I'm not ashamed to admit that I love spending time in cemeteries!
RE: Robert A. Hancock Thanks Jerry, good work! - I actually have a backlog of photos that I've taken of headstones and markers in the Diplomatic & Consular Officers Memorial Area of Rock Creek, but have not had time to add to Find-a-Grave. If only they offered 36-hour-days...
Peyton Lewis Adams (Aug. 22, 1882 - Dec. 24, 1953) Thank you for looking. That sorta explains why his wife Rachel V. Murphy Adams who died in 1968 has her name on her parents stone in Rock Creek. I just assumed Peyton L. Adams was buried there. I will check his obituary again for a funeral home contact.
Ada Young Van Cloostere I just filled your request for Joseph, but it's a duplicate memorial as there is actually an "E" on the end of the name. Ada is in the Van Cloostere mausoleum on the south wall bottom crypt, beneath Joseph. It's very difficult to photograph through the doors, but I will try again with morning light to get a photo of her inscription.
