Robert Puleston was a brother-in-law and supporter of Owain Glyndŵr, at the time of his rebellion against King Henry IV of England in the early 15th century and afterwards.
[1] Pulestons had settled during the reign of King Henry III in Newport, Shropshire initially, in Pilston village and manor, from where they derive their surname.
His forebear Sir Roger de Puleston (died 1294) established himself at Emral in Maelor Saesneg, and was appointed the first High Sheriff of Anglesey by King Edward I of England in 1293.
[2] His first task there was to impose the new English taxes (one fifteenth of all moveables) that unsurprisingly led to the revolt of Madog ap Llywelyn, at the height of which the Welsh mob seized the Sheriff and hanged him following a raid on Caernarvon borough.
However, as part of the programme of Royal Pardons meted out by the new King Henry V he received his old lands back, restored to him after the rebellion had petered out around 1415.
