JONES , THOMAS ( 1756 - 1807 ; DWB , 516).

There remains uncertainty as to his parents. According to the tradition recorded by Williams , Mont. Worthies , he was the illegitimate son of Owen Owen , Llifior , Berriew and there is an entry in Berriew register of baptisms 29 June 1756 Thomas son of Catherine Evans of Llivior ’. ( Owen had married the heiress of Llifior .) In 1760 a case was brought against ‘ Catherine , wife of Mathew Jones of Trefeen , Kerry ’; who had been in service in Tynycoed Llifior . However in Glansevern papers (NLW) 17840 there is a note concerning ‘ Jones of Trefeen illegitimate son of Davies of Ty'ncoed cousin to Miss Davies who married Owen “Welsh Uncle” to David Owen Senior Wrangler ’.
