Thomas Crane was also my great-grandfather (my mother's grandfather). I know only a bit about Catherine Faragher. After William Crane died, she married Solomon Manley and had three children. She died when she was thirty-three and Thomas was seven. At the time of the 1851 census William was living with the Manleys in Patrick, and Thomas was living with his widowed grandfather Clucas Faragher and his uncle Clucas and other relatives. My mother kept in touch with a Woodrow Manley before his death, and she has always referred to him as a cousin. His widow lives in Virginia. I have her address and the addresses of two Manleys who live in the Isle of Man. Maybe they could help you with the Faraghers.
