Send a message to the person who requested a photo of the grave monument of John Sydenham Carpenter with the following comment:
I am researching my step grandmother's family and it has come to my attention that John Sydenham Carpenter Snr is her great great grandfather. Her grandfather was the result of an affair with Sarah Alma Jarvis. The son, William Jarvis, lists John S Carpenter as his father, on his marriage certificate in South Australia in 1900.
