Had this request from a someone in USA.

I have a brick wall with my ancestor Robert Martin, b. about 1803 in Castletown, Isle of Man. He moved to Liverpool and became a building contractor. I have found him in the 1841 Liverpool census with David Martin, perhaps his father. I have his complete family in the various censuses in Liverpool. and I have his death record at age 80 in 1883. But, I would love to have more information about his family at the time of his birth in Castletown. Thank you in advance. Shirley A. Smith (in Florida and Maine)
