This text was sent to me by our American cousin Simon.
My interpretation is that it refers to William Blackledge (1632-1701).
It looks as if he left Anne Goulbourne when his sons Richard and John were coming of age at 22 and 19 years, and emigrated to the States where he started a new family. -  JB

1.     WILLIAM BLACKLEDGE, the founder of the family bearing his name in Pennsylvania, came from England about 1682, and some time later settled in Southampton Township, Bucks County, where he purchased a tract of 270 acres on the west bank of the Neshaminy. He died intestate about 1718.

        He married a daughter of Benjamin Duffield, and some time prior to his death seems to have transferred his real estate to his father-in-law, who in turn conveyed the same in entail to his grandson, Benjamin Blackledge, the eldest son of William, and to his male heirs in succession. This Benjamin Blackledge, who was a tanner in Lower Dublin Township, removed to Johnston County, North Carolina, in 1758, and almost immediately on his removal joined with his son Richard Blackledge of Craven County, North Carolina, in a deed to Samuel Swift, for the purpose of docking the entail, which they succeeded in doing, and Richard Blackledge made a conveyance of the property in fee.

William Blackledige had, besides Benjamin, several other children, among them

Thomas Blackledge, who later settled in Milford Township, Bucks County;

Robert Blackledge, who married Elizabeth Howard, at Christ Church, Philadelphia, June 19, 1732, and

John Blackledge, who married Bridget Grimes in 1736.

Benjamin, above named, married Sarah Philpot, at Christ Church, December 26, 1726.

        2. THOMAS BLACKLEDGE, the first of the family to settle in the Great Swamp, was a son of William Blackledge, and was born in Bucks County in 1707. He was married by New Jersey license dated April 15, 1730, to Elizabeth Randall, both being residents of Bucks County. About this date he removed to Lower Milford Township, Bucks County, and took up land under warrant of survey which was later patented to him. He also purchased adjoining land from Thomas Banks in 1750. On one of these tracts he erected and operated a tannery.

        The family were not originally members of the Society of Friends, but some time after the removal of Thomas Blackledge to the Great Swamp, he and his family united with the Richland Monthly Meeting, of which they continued to be members during their residence in that section. He died in Milford Township 12 mo. 7, 1790, at the age of 83 years.
