This photo is of Shelby Huggins Simmons and his first wife Darlutha, and their baby daughter Truckee. This was taken about 1856. Truckee was born while they were headed west in a wagon train. She was born in Truckee, California on their journey.
(Shelby is my second great-grandfather. His second wife is our family line. Shelby is the father of Clay Taylor Simmons.)
