I have just googled the name of my Great Grandfather - George Arthur Trevelyan and found this link. I am from New Zealand and have also got a reasonably extensive tree on the Trevelyans but would love to find out more about the Cornish trail and would like to start on the trail of Mary Charlton, George's wife. I understand she was born in Ireland?? My Grandmother was Edith Charlton Trevelyan who married Albert Edward Rockell and my father was their youngest son, Trevor Albert Rockell.
If anyone is still following this post would love to hear from you.
