Moses Ball was born in 1717, the second son of John Ball and Winifred Williams of Hunting Creek, Overwharton Parish, Stafford County, Virginia.  He married Anne Brashear(s) 27 July 1745 at Stafford County.  Anne was a daughter of Robert Cager Brashear(s) and Charity Dowell, and had not yet reached her fifteenth year when she married Moses, he being 27 years of age.  Moses and Anne had a family of eight children from 1746-1762.  When Moses reached his majority in 1739, he received land from his father's estate, who had died in 1722.  From John Ball's Last Will and Testament, is written: "I give and bequeath unto my son Moses Ball all the land and plantation and Water Mill that belongeth to me on the north side Great Hunting Creek to him and his heirs lawfully begotten and in default of such heirs that then to fall to the next male heirs forever."  This property is near present-day Alexandria, Virginia.  He added 91 acres to his land holdings in late December 1745.  Moses was the older brother of Lieutenant James Ball, who served in the Revolution, and was identified as such in a Fairfax County Court held in 1835.  Moses' first and fifth sons, John and George, respectively, also served as officers in the Revolution.  Moses was 59 years of age when the Revolutionary War began.  He and his family supported the Patriot cause with enthusiasm.  Moses paid all required taxes and provided material support to the war effort.  

George's mother was Mary Ball.  Family tradition claims a distant relation to the first President of the United States, however; no direct connection has been proven.  Moses is mentioned on two occasions in George Washington's Day book after the war in the 1780s, being that his property bordered Washington’s.  On one occasion, Moses borrowed ten pounds from George to pay a debt.  In Moses' Last Will and Testament of 1792, this debt is addressed in detail.  Also in his Will, Moses identifies land that borders the Mount Vernon estate:  "I give and bequeath unto my well beloved son, John Ball, twenty five acres of land, beginning on the south side of Four Mile Run at the White Oak of General Washington's, thence with Washington's line to Alexander’s line and the meanders of Long Branch Westwardly until the quantity of twenty-five acres is made then with a Southerly line from the Long Branch to said line of Alexander."  Within 25 years of Moses' death, his land holdings were lost to the family due to foreclosure.
