Annie, Thanks for the email. <<My late cousin who had this line told me that all the Herberts in Cardiganshire came out of the Herbert family of Rhiwbren, Llanarth Parish, CGN.>> I don't know if it is really all the HERBERTs in Cardiganshire, but if its not then it is most likely most. The people I have talked to think that all the HERBERTs in and around Llanarth are descended from Morgan HERBERT who died 1643. He had a number of children but to my knowledge only two lines have been researched with any certainty. <<There is supposed to be some relationship to the Earl of Pembroke.>> Morgan HERBERT was descended from Sir Richard Herbert, the brother to the 1st Earl of Pembroke. <<The family that I am related to was headed by Thomas Herbert of Llanddewi Brefi, CGN.>> That sounds interesting. Thomas is a name that is in my tree as well. As name inheritance is common (although not absolute) there could be some link here with my tree. Is your tree avalible? Thanks Andrew
