I have meant to go through your early data and compare your findings with mine. I am beginning to see you have many of the individuals I have encountered. For example you have a Robert b. 1167 in Suffolk and a Curia Regis Rolls notation for 1212. I haven't seen that,however I found a Curia Regis Rolls notation for Robert Carpenter married to Christina for 1253. The Suffolk Carpenters seemed to me a distinct group i.e. that had capital for land. There was a Thurston and a John of Butley Carpenter for 1230-32. All of the above might be descendants of Ralph Carpenter who is listed for land aquisition in both Norfolk and Suffolk for 1225-26. In 1272 in Sallop, a Robert is noted as son of Radulphus. There was also a John son of Ralph noted for Norfolk. I question the 1212 date for Robert. Is there even Curia Regis Roll data that early? Where was Sallop? BC
