These parents: Elizabeth (Lukens) Tyson Rockhill (1730 Horsham, Montgomery County, Pennsylvania, Colonial America - April 07, 1798 Philadelphia, Philadelphia County, Pennsylvania), daughter of William Lukens and Elizabeth Treyphers Lukens (Tyson) married Thomas McVeagh Potts (1729 Upper Dublin, Montgomery, Pennsylvania, British American Colonies - July 29, 1776 Chelsea Forge, Sussex, New Jersey, United States)
are credited with having two daughters named Rebecca, both of whom survived infancy and had children of their own:
*Rebecca Bone (1766 - c1822) married John Abner Bone, Jr.
*Rebecca Yongue (c1766 - c1851) married Rev. Samuel Whorter Yongue
As this situation is highly unlikely, it appears that two families have been intermingled. A MyHeritage family tree appears to be the source of the confusion. Do any profile managers or descendants have information that could be used to sort out the families?
