Researching my husband's family and I think he is descended from Richard Mollon also. It seems their grandson, Thomas, born 1841 in Poundstock to Joseph, came to Canada also. He married Frances Kinsman and they had two children, Herbert and Frances. He died somewhere between 1877 and 1881. Spelling is Mullen. I think it's correct as the Kinsmans emigrated from Stratton, Cornwall also.
