The first Gregg of record found in America was Thomas in 1648, in Northumberland County, Virginia. This date was shown as a land record by George Cabell Greer, clerk of the Virginia State Land Office in 1912, in his book, Early Virginia Immigrants, 1623-1666. Northumberland County was formed in 1648. It is not known if Thomas immigrated to America from Scotland or Ireland. He probably arrived in America immediately prior to, or during the year 1648. Thomas Gregg patented 400 acres of land in Westmoreland County (formed from Northumberland County in 1653) on the branches of the Pasbatacy Creek, 18 March 1662. This land afterwards fell in Stafford County, and later in King George County. Thomas was a Justice of the Peace in Stafford County in 1680. He was appointed to the “Commission of the Peace” by William III, King of England in 1700, and again in 1702. In 1691, Thomas Gregg, Sr., refused to take the oath of allegiance to William and Mary – he evidently adhered to King James II as his rightful sovereign. Thomas married Lucy Heabard, and preceded her in death. No record of his death or will could be found. Lucy Heabard Gregg’s will was dated 9 January 1730, and admitted to record 11 March 1730. She (Lucy) named grandson Edward Humston as Executor. The only other member of the family named in the will was a granddaughter, Sarah Newton.  The children of Thomas and Lucy Gregg were:

Thomas, Jr., was probably born before 1670, as he appears to be 21 years old in 1690, as indicated by a Stafford County court record of July 19, 1690. He received a land grant 25 January 1694, of 200 acres on the Potomac Creek in Stafford County. Thomas Gregg, Jr., in 1692, was a lieutenant in the Virginia Militia. He married Lucy Grigsby, daughter of Thomas Grigsby. The only known child of this union was a daughter, name unknown, who married Edward Humston.

James Gregg was mentioned as “brother” in a deed of Thomas, Jr., in 1706. The will of James Gregg was recorded in missing Will Book K, (1721-30). An inventory of the estate was filed in the same book, according to the general index. John, brother of James, served as Executor, and the estate was divided May 29, 1734, among the following children: 1. Mathew, married Cathrine –, his will was made in 1749, and probated 9 August 1757; their children: i. James, b. 18 May 1740; ii. John, b. December 1744.  2. John; 3. Sarah, m. William Brown; 4. Letitia; 5. Jeremiah.

John Gregg was a Justice in 1730. His will dated 14 January 1743, named his wife Elizabeth; daughters Jean and Mary, and an unborn child.  Bond made in connection with the will, was 25 April 1743, with inventory of the estate filed in Stafford County.

Elizabeth Gregg, married Benjamin Newton II.
