John Bacon, son of Captain Edmund and Anne Lydall Bacon was born in 1683 in New Kent County, VA. He married first Sarah Langston who died 4 January 1709/1710. He married a second time to Susanna Park, daughter of John Parke. 
John patented land in 1701 that had been patented by his father Edmund in 1687, and John passed the plantation to his son Edmund, who was his only son then remaining in New Kent Co. John was sheriff of New Kent County and a vestryman of St. Peter's Parish, as his father had been. In 1707, John Bacon was ordered to assist in clearing roads in New Kent County.  He also served as Burgess from before 1727 until 1742.
John and Sarah's children were:
1. Nathaniel, b. 14 Aug 1708
2. William, b. 30 Dec 1709, patented land in Henrico Co. in 1749 and was living there as late as 1788.
Note: Several sources, including James, cite the New Kent County St. Peters Parish register for the identity of John and Sarah's children; however, P. Fall Taylor says that the register was "mutilated," that only the dates of birth are legible, and that their names were identified through "other sources."

It may be possible to confirm family relationships with John by comparing test results with other carriers of his Y-chromosome or his mother's mitochondrial DNA.
However, there are no known yDNA or mtDNA test-takers in his direct paternal or maternal line.
It is likely that these autosomal DNA test-takers will share DNA with John:
I'm interested in any documentation of john's marriage to Sarah Langston or any evidence linking John as son of Edmund Bacon and Ann Lyddall. I know the name lyddall was used for years as a first or middle name in subsequent generations, about the plaque in the church and that john repatented Edmunds land in 1701. Just hoping that there might be something else even more definitive that has come to light
