I am very interested in this line of quesioning. I have traced my line back to Jirah Martin via his daughter Hannah who married William King. As for your Samuel Wilber King. I have he married 1st Mehitabl Bacon, their third child Phebe married Wilson E King s/o James and Hannah s/o James and Betsey s/o James and Deliverence- I'm trying to connect my William King to this line.
Now the online info on Jirah, I have he's s/o Stephen Martin and Patience Pope s/o John Martin and Jane Flanders s/o John Martin and Mary Weed s/o George Martin and Susannah North. If I have any of this incorrect, I'd like to make the correction.
