Lee, Have you found any siblings for your Jacob? My first Hooker shows up as Henry Hucker, getting married in Boston, MA in 1708 to Elizabeth Helyer/Hilliard. His estimated birth year is 1685 which might make him a sibling of your Jacob. After more than 30 years of looking I still haven't found the parents or origins of my Henry Hooker. I have seen mention that some of the Hookers may have come from the Isle of Jersey in the Channel Islands as there were some who ran ferries on the MA coast north of Boston. In the index of a book on the Channel Islands under Hooker I found Ocker (they spoke more French than English), Auker, etc. In Ipswich, Essex Co., MA there was a Jacob and a John born to Matthew Hooker and his wife Rachel in the 1680s and '90s. Good luck! Carole in Portland, Oregon
