You have peaked my interest in a couple of ways. 1. A Palmer Pinckney md. my g-aunt, Emily Grant around 1916-1917. She was from Savannah, Ga. and i've heard he was from SC (don't know where). I think, I found him in 1920, in New York, saying he was from NC. She's in Sav. with her dau. Wille. 2. As you can see I too, am a Grant, from Ga.
This part of my family I haven't started to research. You may give me the spark to start.
