No, I've put a bio on Anna and her correct father. Abigail is not the daughter of this father either. At least according to the Curtis/s Family society. They rely heavily on a book (Harold Everdell Curtis, Descendants of Thomas (1), Richard (1) and William (1) Curtis of Scituate, Mass. - 1638) that I've never seen although I have no reason to doubt it's accuracy.
It is an incredibly complicated family with lots of misinformation
