Hi Cindy! I am the great granddaughter of Robert Lawrence. My grandmother ( Robert L's daughter, Lois) always told us that George Washington Evans was not Robert's real father. She never knew who his real father was but that it had been kept a secret. If you have any information on his father please contact me! We would love to know. My grandmother is still living and I would love to tell her this information. You say the true blood line is Cole- who was this Cole family? It would be great if you could get back to me!
