Before the middle of the 15th cent. a branch of the family had settled at Berse, near Wrexham , and by the end of that century Hafod-y-wern, in the same area, had come into possession of the Pulestons through the marriage of JOHN PULESTON of Plas-ym-mers, a grandson of the Robert and Lowry... and Alswn, daughter and heiress of Hywel ap Ieuan ap Gruffydd of Hafod-y-wern. JOHN PULESTON (‘HEN’), of Hafod-y-wern , the eldest son of this John Puleston, fought at Bosworth, and for his services on that occasion received a grant for life from Henry VII of an annuity of twenty marks out of the tithes of the lordship of Denbigh ( 6th Report Royal Commission on Historical MSS. , 421), and was appointed a gentleman usher of the king's chamber. In 1502 he was made deputy-lieutenant to the chief steward of Bromfield and Yale (ibid.), and seven years later, in 1509, Henry VIII granted him the receivership of the town of Ruthin and the lordship of Dyffryn Clwyd (Cal. L. & P. Henry VIII , i, 1, 67), and in 1519 that of the lordship of Denbigh and Denbighland (ibid., iii, 1, 146). Like his kinsman, Sir Roger Puleston, he served in the French campaign of 1513, as also did his two sons, both named John, the one by his first, and the other by his second marriage. JOHN PULESTON, of Hafod-y-wern (‘John Puleston of Tir Môn,’ as he is sometimes described), son of John Puleston (‘Hen’) by his second wife, Alice, daughter of Hugh Lewis of Presaddfed, was sheriff of Denbighshire, 1543-4. During the latter years of Elizabeth I, two of these Pulestons were presented for recusancy at the Denbighshire Great Sessions : EDWARD PULESTON, of Hafod-y-wern, in 1585, 1588, and 1592, and Anne , wife of JOHN PULESTON, of Berse, in 1587. 3

Siôn ap Siôn ap Madog Puleston was rewarded by Henry VII for his loyalty in the battle of Bosworth in 1485, and went on to hold a number of influential offices in north Wales. In the following century, a sub-branch of the Pulestons of Hafod-y-wern was established in Caernarfon by this Siôn’s son, Sir Siôn Puleston. 5
