Hi, I am a direct decendant from Houghton, still living in Cornwall. If you go to http://gwennap-opc.tripod.com/contents.htmhttp://gwennap-opc.tripod.com/contents.htm you will find more information on the Gwennap area. I have managed to trace Houghton parents to be Mathew Vivian b.1754 married to Genefer possibly Morcom b. 1763. I would love to make contact with any decendants and possibly update and add to my records.
