I have added Abigail Haskins Jackson as a daughter of Sarah Carker. On page 240 of the OpDyck Genealogy, she is said to have shared the same mother as the second wife of John Updike the tailor of Loudoun County, Virginia. I don't know if it will help us get any closer to the truth or not, but apparently the family originated in Burlington New Jersey.
Note: I very nearly added unicorn to the tags because this family seems to be composed of mythical creatures.
