Notes
https://en.wikipedia.org/wiki/Joscelin_of_Louvain
Joscelin of Louvain, also spelled Jocelin de Louvain and Jocelyn of Leuven,[2][3][4] 
(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.
Origins[edit]

He was a son of Godfrey I, Count of Louvain either by his second wife, Clementia of 
Burgundy, or by a mistress.

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.[5] Upon his 
marriage, he adopted the Percy surname.[6]

Petworth[edit]

Main article: Petworth House

Joscelin was granted the manor of Petworth, in Sussex, by his sister Adeliza, the 
widow of King Henry I of England.[2][7] His descendants were seated at Petworth 
House for many centuries.

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.[2]

Marriage and progeny[edit]

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[5] 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.[5]
Richard de Percy (d.1244), younger son, who inherited from his mother her moiety of 
the barony of Topcliffe.[5] 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.[5] He was a Magna Carta surety.
