Rose Dixon was born in Ireland to Henry and Rose Dixon in 1661. She came to America with her brother William, her sister Dinah, and her widowed mother when "he joined the Quaker emigration from Ireland and came again to America, to William Penn's Colony of Pennsylvania, in that portion which now is Delaware, in 1688." They were members of the Newark Monthly Meeting in New Castle, Delaware, where Rose married the widower Thomas Pierson in 1690. Thomas was a Deputy Surveyor of New Castle county Del.
They had two daughters, Rose and Susanna.
Rose Pierson died in 1722.
It appears that some profile merges at one point added several children for Thomas & Rose (Dixon) Pierson, but that the Thomas shown as father of those children was not the son of Susanna. Two Thomases, one son of Susanna and one not, were merged, which added extra children to the Rose we know married Thomas son of Susanna. That Rose was William Dixon's sister and she and Thomas had two daughters, Susanna and Rose. Perhaps another Rose married another Thomas Pierson (Pearson?) and had many children, including daughters named Susanna and Rose, or there was some other explanation. (The extra children have been separated from this Thomas & Rose; they are listed under the "other" Thomas, son of Lawrence and Elizabeth (Janney) Pearson.) The original profile imported with Glenn Dixon's gedcom for daughter Susanna stayed with the new family, since there are already two WikiTree profiles her (Pierson-480 and Pierson-243).
Both Roses are shown as the daughter of Henry and Rose Dixon. Ken's Rose (Dixon-1319) shows that she was born in 1661 in Ireland, her mother's maiden name as Harlan, and no listing for a spouse. Glenn's Rose shows that she was born in 1670 to mother "Rose Unknown" and married in 1690 Thomas Pierson.
Quakers in Delaware in the Time of William Penn (http://nc-chap.org/church/quaker/standingDH3crop.pdf), by Herbert Standing, says that Rose Dixon came to America with her brother and widowed mother. It also says that Thomas Pierson, son of Susanna Pierson, married Rose Dixon after the death of his first wife:
