Sir Hugh Purcell

The earliest documented Purcell is the Norman Hugh Purcell, who, in 1035 AD, granted the tithes of Montmarquet, a vill on the frontiers of Picardy, and near Aumerle, to the Abbey of Aumerle. The successor of Sir Hugh Purcell was Dyno Purcell, who in about 1120, received a grant of the manor of Catteshull, Surrey, from King Henry I. Catteshull is a manor and tithing the north-east of Godalming (Surrey), and included lands in Chiddingfold. Øyno married a daughter of Nigel de Broc, a famous Justiciar of the time. In 1129–30, his elder son Geoffrey, the King's usher (hostiarius), paid his relief for his father's land and held it free of toll as it had been in his father's time, and gave it to Reading Abbey on becoming a monk there. This gift was confirmed both by the Empress Maud and by her opponent Stephen. No mention is made of Catteshull in the confirmatory grants of Henry II to Reading Abbey, and he seems to have regranted it to Ralph de Broc, son of Øyno Purcell (identical with Ralph Purcell), to hold by the service of usher of the king's chamber.

Hugh Purcell married the daughter of Theobald FitzWalter, Beatrix FitzWalter. As part of the marriage, Hugh received a dowry from Theobald, consisting of a town by the name of Loughmoe in Tipperary. Here, Hugh constructed a castle, Loughmoe castle. Beatrix had a previous husband; Thomas de Hereford[9] or Thomas de Hungerford.[5] According to O'hart, Beatrix was only a child when Thomas died, "thus the heiress to a splendid inheritance".[5] Theobald was the cup bearer to King Henry II.

Geoffrey's brother and heir, Ranulf, assumed his mother's name of De Broc apparently in 1156, as the Pipe Roll of that year for Hampshire he is styled De Broc and for Surrey he is still called Purcell.

Dyno's son, Ranulf Purcell, took his mother's name, de Broc, and was implicated in the assassination of Thomas Becket. Ranulf was excommunicated for theft of property of the Archbishopric by Becket, on Christmas Day, 1170, the traditional day of forgiveness. When Henry II, who was in Normandy, heard of this, he is said to have asked why none of his knights had rid him of "this troublesome priest". A few days later, four knights arrived at Saltwood, Ranulf de Broc's castle in Kent. After the murder, Saltwood was confiscated by Henry for De Broc's involvement in the murder. De Broc argued that the knights had lied to him and said Henry had ordered Becket be arrested.

Just as Randulf de Broc had no male issue, neither had his nephew Robert, who as Justiciar is frequently mentioned in the public Records; Robert came to be represented by the De Lodges' and the Peto's.

The Purcell male representation then passed to the family of the lords of Newton-Purcell Oxon., and Shareshull, Staffordshire. Ralph, the founder of this line, inherited those manors and others in Normandy, near Rouen, together with the Court Office, viz.: Usher of the King's Chamber, as well as his maternal uncle Robert Burnell's Court Office of Usher, who was living in 1129–30 and enjoyed the Royal favour shown by the remission of the Dane-Geld. About 1154, a charter of confirmation of his uncle's lands and office passed attested, among others, by St. Thomas a Beckett, the Chancellor. About 1160 he made a grant of land in Normandy to the Abbey of the Holy Trinity, Rouen. He must have lived to a great age, as he obtained another confirmation under the payment from King John A.D. 1200. He was the Patriarch of a numerous tribe in England and Ireland; one of his sons being Hugh, who took part in the English Invasion of Ireland in 1171 and became the founder of the House of Purcell in that country.
