Thanks for your message - I believe Robert Chick (b N Petherton abt 1818) was my Great, Great, Great Grandfather.
His son, Robert, b 1854, moved to Pontypridd in S Wales before 1874 when he married Elizabeth Martin (orig from Lugdvan in Cornwall).He was a stonemason like his father. They had at least 6 children that I know of: Bessie Florence (b1875), Elzabeth (b1879), Robert (b1881), Ethel Maud (b1888), Eva (b1896) & Elionor (b1898).
Bessie Florence was my Great Grandmother and she married John James Legg on Christmas Day 1900. (He was originally from Exeter via Bridgwater and worked as a coal miner in Pontypridd).
Ethel Maud married a baptist minister - David Gunn Sutherland - and eventually settled in Rothesay on the Isle of Bute in the Firth of Clyde.My grandmother, Ethel Marjorie, lived with them for a long period and it is there she met my grandfather, Thomas Mitchell.
Does this have any connection to your link with Martins in Pontypridd?
