Answer 2

Bambrough
This interesting and unusual name is of medieval English origin
and is a dialectal variant of "Bamborough", from a place so
called in Northumberland, where the surname is still prevalent.
Bamborough or Bamburgh was built by King Ida in 547 according to
the "Handbook to the land Charters", and is recorded as
"Bebbanburh", after a former queen "Bebba" of Aethelfrith, the
second element is a derivation of the Old English "Burh", a
fort. The placename is also recorded as "Bebbanburgh" (890),
"Baenburg" (1130, Pipe Rolls), and Banburg (1212, Fees). During
the Middle Ages when people left their birth place to seek work
elsewhere, they would often adopt the placename as a means of
identification. One Matthew Bambrough was christened on
September 21st 1662 at Berwick-upon-Tweed. The first recorded
spelling of the family name is shown to be that of
Rachiell Bambrough (marriage to George Hymon), which was dated
February 3rd 1653, at Newcastle-upon-Tyne, during the reign of
Oliver Cromwell, known as "The Great Protector", 1649 - 1658.
