Hyde Family of Denchworth

The Hyde family of Denchworth in the English county of Berkshire (now Oxfordshire) were a landed family from at least the Norman period to the late modern era. They were chiefly seated at various places in Berkshire, but there were major branches in County Cork in Ireland. Members have included an abbot, a Knight of the Bath and a number of MPs and high sheriffs. Douglas Hyde of County Roscommon (who descended from the Cork branch), became the first President of Ireland in 1938. They are not related (except by marriage) to the noble Hyde family of Wiltshire and Cheshire.

According to Families of County Cork, Ireland: From the Earliest Times to the 20th Century: Irish Family Surnames with Locations & Origins, Including English, Scots & Anglo Norman Settlers and Settlements (1999) by Michael C. O'Laughlin, the Hydes (his maternal ancestors) held lands in County Cork since 1599. That year the forfeited estates of Gerald FitzGerald, 15th Earl of Desmond, leader of the Desmond Rebellions, were distributed to new land owners "for the purpose of planting them with English settlers". One Arthur Hyde received 6000 acre of land in County Cork. Twenty-four settlers were arranged to cultivate his new lands. The family seat was Castle Hyde, a mansion on the "north bank of the Blackwater River". The Hydes held their estates to the Victorian era when they sold them to Sir Henry Wrixon-Becher, 2nd Baronet (1826–1893).

In 1234, Roger is recorded already holding La Hyde.

The ancestry of Roger is recorded in various editions of the Landed Gentry but its accuracy has been questioned. His father Gilbert de la Hyde was reportedly a brother of John of Wallingford, Abbot of St Albans Abbey. His paternal grandfather Ralph de la Hyde (d. 1156) and John de la Hyde (d. 1135) are only known by name. Their original estate "La Hyde de Southcote" seems to have been replaced in time by other family seats. Unknown is when their estate was established. Family tradition in the 17th century placed their origins in the time of Canute the Great, a claim not mentioned in early sources.
