According to the bio of Rev. Thomas Burges, he and Mary only had one child:

Burges was married first in 1742 at Indian Springs in Southampton County, Va., to Miriam, surname unknown. Indian Springs was the glebe for Nottoway Parish and had been given to the vestry by Francis Clements in 1721. Mrs. Burges died in 1758 at age forty-two, leaving a son and two daughters. In 1760, in North Carolina, Burges married Mary, the daughter of Colonel John Haywood and his wife, Mary Lovatt. Burges's mother was a Lovatt, and the families may have been related. Of the children by his first marriage, Anna Maria married General Laurence Baker of Gates County and Dorothy married Colonel John Bradford of Halifax. The son, Henry John, was ordained by the Bishop of London in 1768 and on his return to America served at St. Mary's Parish, Edgecombe County, for a year. In 1772 he became rector of Newport Parish, Isle of Wight County, Va. An active patriot, he was a member of the committee of safety of the county in 1775 and later was imprisoned by the British. Thomas's son, Albridgeton S. H., attended The University of North Carolina, 1805–9, and became a physician. He lived in Raleigh for a time and was one of the founders of Christ Church there.

Burges and his second wife had only one child, a son, Lovatt, who was clerk of the Halifax County Court for many years.

so his other children other than Lovatt would have been 1st wife Miriam's children.
