Colonel Ninian Beall lived a long and interesting life. He had been born in Largo, Fifes Shire, Scotland, in 1625. There he had been an officer in the Scottish-English Army, which fought for the Stuarts' Army against Cromwell; he was made a prisoner at the battle of Dunbar, September 3, 1650, and sentenced to five years servitude in the Barbadoes, West Indies. Many gentlemen were so sentenced as political prisoners and sent out as industrial servants at that time. He was eventually sent to Maryland, where, after completing his term of servitude, he proved his right to 50 acres of land and received many hundreds more for bringing out immigrants and settling there.

He held many notable and honorable offices in the colony, and, in 1699, the General Assembly passed an Act of Gratitude for the distinguished Indian services of Colonel Ninian Beall.

As he was Commander in Chief of the Provincial Forces in Maryland, he probably visited the garrison at the Falls and so knew this region long before he was granted this tract of the Rock of Dunbarton. He previously had procured 225 acres on the east side of Rock Creek just opposite, called Beall's Levels.

Ninian Beall died in 1717 at his home, Fifer Largo, near Upper Marlboro, Maryland. From a description of him in the Records of the Columbia Historical Society:

... "He had a complexion characteristic of his nationality, with an unusually heavy growth of long red hair, and was over six feet in height, powerful in brawn and muscle and phenomenal in physical endurance."

He had twelve children, six sons and six daughters. In his will is recorded:

"I do give and bequeath unto my son George, my plantation and tract of land called the Rock of Dunbarton, lying and being at Rock Creek, containing four hundred and eight acres, with all the stock thereon, both cattle and hogs, them and their increase, unto my said son, George, and unto his heirs forever.

"I do also give and bequeath, unto my said son, George Beall, his choice of one of my feather beds, bolster and pillow and other furniture thereunto belonging, with two cows and calves and half my sheep from off this plantation I now live on, unto him and his heirs forever."

This son, George, was the eighth child of Ninian Beall. He had a son, Thomas, who always styled himself Thomas Beall of George; of him we shall hear more later on. The family was not limited to these, for many other Bealls, men and women, appear in the annals of George Town.

George Gordon, the other of the two original proprietors of the lands which became George Town, was also a Scotsman and had a share in a manufacture at Leith, near Edinburgh, so it is evident that, when he came to this country, he had means which he invested in Prince Georges County and Frederick County, Maryland. He held the office of Sheriff of Frederick County and was a judge of the first County Court.
