Eustace III, Count of Boulogne
Eustace III (died c. 1125) was the count of Boulogne from 1087, succeeding his father Count Eustace II.
His mother was Ida of Lorraine.
In 1088, Eustace supported the rebellion against William II of England in favour of Robert Curthose.
Eustace participated in the First Crusade of 1096 along with his brothers Godfrey of Bouillon (duke of Lower Lotharingia) and Baldwin of Boulogne.
It is unclear whether he travelled eastward with his brother Godfrey's or Robert Curthose's army.
His contingent included Hugh II of Saint-Pol and his son Engelrand, Eustace I Granarius, lord of Sidon and Caesarea, Fulk of Guînes, and Hugh of Robecq (Rebecques), lord of Hebron.
Throughout the crusade Eustace assisted Godfrey.
Eustace was present at the Siege of Nicaea (May–June 1097), helped rescue Bohemund of Taranto's beleaguered troops at the Battle of Dorylaeum (July 1, 1097), defeated an enemy ambush during the Siege of Antioch and was one of the commanders during the capture of Antioch on June 3, 1098.
Eustace was a member of the council held at Ruj on January 4, 1099, mediating in the conflict over the control of Antioch between Bohemund of Taranto and Raymond IV of Toulouse.
Early December 1098 Eustace joined Raymond's attack on Maarrat al-Nu'man and an attack on Nablus in July 1099.
He gained notoriety for his actions during the Siege of Jerusalem fighting relentlessly from a siege tower along with his brother Godfrey and the warriors they commanded.
They were among the first to breach Jerusalem's city walls and participated in the ensuing massacre.
Finally Eustace commanded a division of the crusader army during the Battle of Ascalon.
While his brothers stayed in the Holy Land, Eustace returned to administer his domains.
To commemorate Eustace's crusading adventures the mint at Boulogne struck silver coins with a lion above the walls of Jerusalem stamped on the obverse.
Eustace married Mary, daughter of King Malcolm III of Scotland and Saint Margaret of Scotland.
Eustace and Mary had one daughter:
When his youngest brother king Baldwin I of Jerusalem died in 1118, the elderly Eustace was offered the throne.
Eustace was at first uninterested, but was convinced to accept it; he travelled all the way to Apulia before learning that a distant relative, Baldwin of Bourcq, had been crowned in the meantime.
Eustace returned to Boulogne and died about 1125.
On his death the county of Boulogne was inherited by his daughter, Matilda, and her husband Stephen de Blois, count of Mortain, afterwards king of England.
Eustace founded the Cluniac house of Rumilly and was patron of the Knights Templar.

Mary of Scotland, Countess of Boulogne
Mary of Scotland (1082–1116) was the younger daughter of Malcolm III of Scotland and his second wife, Margaret of Wessex.
Mary was a member of the House of Dunkeld by birth, and was Countess of Boulogne by marriage.
In 1086, Mary and her sister, Matilda, were sent by their parents to Romsey.
Their maternal aunt, Christina, was abbess there.
The girls spent their early life at the monastery with their aunt, where they also received part of their education.
Some time before 1093, they went to Wilton Abbey, which also had a reputation as a centre of learning, to finish their education.
Matilda received many proposals for marriage but refused them all for the time being.
Matilda finally left the monastery in 1100 to marry King Henry I of England.
The marriage was controversial because it was not clear whether the girls had been veiled as nuns.
Mary herself left the abbey in 1096.
Matilda wanted her to also marry, so Henry I arranged a match with Eustace III, Count of Boulogne.
The couple had a daughter, Matilda, who succeeded Eustace and later became Queen of England.
Mary died in 1116, nine years before her husband.
She was buried at the Cluniac abbey at Bermondsey.
