Source The Boone family; a genealogical history of the descendants of George and Mary Boone who came to America in 1717; containing many unpublished bits of early Kentucky history, also a biographical sketch of Daniel Boone, the pioneer, by one of his descendants, Ella A. Spraker:
The three oldest siblings in the Boone family had come to America a few years before their parents and the rest of the family, who arrived in 1717. Squire accompanied his elder brother George IV and his sister Sarah.
The entire family, along with a number of their relatives, left the Quaker community in PA and moved following the marriage of Squire's eldest daughter Sarah to John Willcockson (Wilcoxson), who was not a member of the faith. After the marriage, Squire was reprimanded by the Meeting, and his explanation appears recorded in the Minutes of Exeter Meeting, Book A, page 33, as follows: (dates are per the Julian calendar) —
"6-26-1742. Squire Boone declareth he did not contenance or consent to the Marriage but confesseth himself in fault in keeping them in his house after their keeping company but that he was in a great streight in not knowing what to do, and hopeth to be more careful for the future."
Some researchers claim that Sarah was pregnant at the time of her marriage to John. The family finally settled along the Yadkin River in North Carolina by 1750.
