In 1751 the Commissioners of Frederick Co. were authorized to purchase 60 acres from George Gordon and George Beall at the mouth of Rock Creek on the Potomac to erect a town called Georgetown. 
"By an act of May 15th, 1751, the Legislature of Maryland provided for laying out a town on the Potomac River, above Rock Creek. For this purpose part of George Beall's land was taken, as well as part of that belonging to Mr.Gordon. When, in spite of their refusal to sell, the land so taken was divided into lots, Colonel Beall and Mr. Gordon were allowed the privilege of first selecting two lots each as compensation for their lands. After a week's reflection, George Beall sent the following answer: "If I must part with my property by force, I had better save a little than be totally demolished. Rather than have none, I accept these lots - Nos. 72 and 79. But I do hereby protest, and declare that my acceptance of the said lots, which is by force, shall not debar me from future redress from the Commissioners or others, and if I have the rights of a British subject, God save King George!"

He died 15 Mar 1780 at Georgetown, D. C. The inscription on his tombstone was as follows: “Herein lieth Colonel George Beall who departed this Life March 15th 1780 Aged 85 years.”

Jourdan then states: "This will does not specifically state what son George is to receive, although it is assumed he was to be given all of the land not given to Thomas. Later land records between George Beall, eldest son and heir-at-law of Col. George Beall, and Thomas Beall, his youngest brother, in an attempt to 'prevent all disputes,' apparently divided the land in a satisfactory manner." 
George and Elizabeth Brooke Beall had twelve children (from the family Bible that belonged to George C. Washington; communicated by Mrs. Henry Irvine Keyser, of Baltimore ):
