From Wikipedia

Eustace fitz John (died 1157) was a powerful magnate in northern England during the reigns of Henry I, Stephen and Henry II. From a relatively humble background in the south-east of England, Eustace made his career serving Henry I, and was elevated by the king through marriage and office into one of the most important figures in the north of England. Eustace acquired a great deal of property in the region, controlled Bamburgh Castle, and served jointly with Walter Espec as justiciar of the North.

After Henry I's death in 1135, Eustace became involved in the warfare between the supporters of Stephen and his rival the Empress Matilda, the latter led by Matilda's uncle David, King of Scotland. He surrendered Alnwick Castle and Malton Castle temporarily to David, while Bamburgh was taken by Stephen. Eustace became a supporter of David, fighting and suffering defeat at the Battle of the Standard in 1138. He maintained most of his lands in the north however, and from around 1144 became one of the main followers of Ranulf II, Earl of Chester, through whom he gained even more land. Eustace subsequently founded three religious houses, and died on campaign with Henry II in 1157.

Eustace's family came from the south-east of England. His father John fitz Richard was a tenant-in-chief who appeared in the Domesday Book owning estates in Essex and Norfolk. The family was not of exalted origin, representing the middle rank of society. Eustace had two known sisters, Agnes and Alice. He also had two brothers, Pain (Payne) and William, and it is thought that Pain—whose career was as successful as Eustace's— was probably the eldest. Eustace likely did not inherit much from his father, but instead depended on success as a royal servant.

Eustace is witnessing royal charters from at least 1119, but may have been at Henry's court as early as 1114. Through Henry's patronage, Eustace married two heiresses, both of whom brought him lands. Beatrix de Vesci, daughter and heiress of Ivo de Vesci, brought him control of Alnwick Castle and the barony of Alnwick in Northumberland. He probably received, in addition, land in Lincolnshire as well as five and a half knight's fees in Yorkshire previously belonging to Ranulf de Mortimer (died 1104). Although it has often been claimed that this marriage brought Eustace the lordship of Old Malton, a former royal manor in the North Riding of Yorkshire, this was probably a separate gift from the king.

Eustace's marriage to Beatrix occurred some time before 1130.
The other marriage, which also occurred before 1130, was to Agnes daughter of the constable of Chester William fitz Nigel, and this eventually brought Eustace more land in Yorkshire at Bridlington as well as in Northamptonshire at Loddington. Both landholdings were held from the earl of Chester. Eustace would gain control of many other sub-tenancies, held from a number of lords, including the Archbishop of York, Bishop of Durham, Nigel d'Aubigny, and the count of Aumale, and in Henry's reign he held lands at Aldborough, Tickhill and Knaresborough from the king as a tenant-in-chief.
...
Eustace had a good relationship with Stephen's successor Henry II, and the latter seems to have regarded Eustace as one of his supporters. Henry confirmed Eustace's gifts to his son William de Vescy, and would recognise the latters succession to his father's lands. After Henry's accession in 1154, Eustace attested the new king's charters. Eustace died in July 1157 near Basingwerk in Flintshire, where on campaign with Henry against the Welsh he was ambushed and killed.
...
Eustace Fitz John married firstly Beatrix de Vesci, daughter and heiress of Ivo de Vesci, and had the following known issue;
1. William de Vesci (d. 1184), married Burga, daughter of Robert III de Stuteville, had issue. William was the sheriff of Northumberland between 1157 and 1170, and would become the ancestor of the Northumberland de Vescy family.

Beatrix is recorded to have died in childbirth. Eustace married secondly Agnes de Halton, daughter of William fitz Nigel, and had the following known issue;

2. Richard fitz Eustace (d.c. 1163), married Aubrey de Lisours, daughter of Aubrey de Lacy and niece of Ilbert II de Lacy (another baron captured by Earl Ranulf at the Battle of Lincoln), had issue. He became ancestor of a second line of de Lacys.
