Bohun

The de Bohun were a Norman family founded by Humphrey with the Beard, who held Bohon on the Cotentin Peninsula and settled in England after the Conquest. Henry de Bohun became the first Earl of Hereford and Constable of England in 1199. The family held lands in the Welsh Marches and took the swan as its heraldic badge.

The fourth earl was one of the Ordainers who curbed Edward II and married Edward I's daughter Elizabeth of Rhuddlan in 1302; he was killed leading the rebel charge at Boroughbridge in 1322. His daughter Eleanor married James Butler, first Earl of Ormonde.

The last male heir, the seventh earl Humphrey, joined the sack of Alexandria in 1365 and died in 1373 leaving only daughters. The estates passed through his daughters Eleanor to Thomas of Woodstock and Mary to the future Henry IV.
