Joscelin of Louvain, also spelled Jocelin de Louvain and Jocelyn of Leuven, (1121–1180) was a nobleman from the Duchy of Brabant who settled in England having married an English heiress. Through his youngest son, the House of Percy — as the Earls and later the Dukes of Northumberland—became the most powerful family in Northern England. He was brother-in-law to King Henry I, whose second wife was Joscelin's half sister Adeliza of Louvain.
He married Agnes de Percy (d.1203), one of the two daughters and co-heiresses of William II de Percy (d.1174/5), 3rd feudal baron of Topcliffe, Yorkshire. Upon his marriage, he adopted the Percy surname.
Though they originally intended Petworth to be their southern home, the Earls of Northumberland were confined to Sussex by Elizabeth I in the late 16th century, when she grew suspicious of Percy allegiance to her rival, Mary, Queen of Scots. Petworth then became their permanent home.
Marriage and progeny
He married Agnes de Percy (d.1203), one of the two daughters and co-heiresses of William II de Percy (d.1174/5), 3rd feudal baron of Topcliffe, Yorkshire and settled in England. He and his descendants, later created Earls of Northumberland, adopted the surname Percy. By his wife he had at least seven children:
- Henry de Percy (d.1198), eldest son, who predeceased his mother and married Isabel de Brus, daughter of Adam de Brus (d.1196). He was survived by a son William III de Percy (1197-1245), who inherited from his uncle Richard de Percy (d.1244) his grandmother's moiety of the barony of Topcliffe.
- Richard de Percy (d.1244), younger son, who inherited from his mother her moiety of the barony of Topcliffe. He himself died without issue when his heir was his brother's son William III de Percy (1197-1245), who thus regained the whole of the Percy barony of Topcliffe, having inherited the other moiety from his great-aunt Maud de Percy (d.1204), sister of Agnes. He was a Magna Carta surety.
