Cross your fingers, all descendents and pass this on to whoever might be interested.
I think I have located the hometown and parish of Samuel Farwell of Marblehead in England. At least, I found probate records of an Absalom Farwell with sons Samuel and John in Poole, Dorset, England in the early 1700s. There are Fosters there as well.
The vital/church records are not easy to access, however. They are in the Dorset Public Records Office in Dorset. So if anyone is near there or going there, be sure to do lookups. I'm going after I save the money to go.
I can't read all of the wills because some of the handwriting is chicken scratch, but I am going to ask for help at the Family History Library.
