She told visitors to travel north on Peachtree Road past Oglethorpe University and then turn left. Their house was the was the first one drivers would see.

The Tilly School once sat about where the Crossroads Church of Dunwoody is located, at the intersection of Peeler Road and Tilly Mill Road. Prior to Crossroads, this was the location of North Peachtree Baptist Church.

The Tilly School, Tilly Mill, and Tilly Mill Road were named for the pioneer Tilly family that owned the land and had a home, farm and mill in the stretch between Peeler Road and North Peachtree Road. The family operated a cotton gin, sawmill and gristmill on their Dunwoody land.

The oldest home in Dunwoody is in Sellars Farms Subdivision. Originally it would have been on what is now Roberts Drive, but today the address is 5660 Glenrich Drive in Dunwoody. There is a historical marker which identifies the house as the Larkin-Martin home, circa 1840.
