As you mentioned possible matches in Forehoe, which is in the Wymondham area, I have a book "Wymondham in the Seventeenth Century", so had a look at their index and found the following. "From 1633 to 1630 over 200 people are known to have emigrated from nearby Hingham in Norfolk to what is now Hingham in Massachusetts. Their names and the Norfolk places they left were recorded by the Reverend Peter Hobart in his Journal and by DANIEL CUSHING, whose father received land in Massachusetts in 1638 and who himself received land in 1665. He was the Town Clerk and a magistrate, while Peter Hobart was the Town Minister from 1635 to 1678."
