Jone was the fourth child of George and Johan Jewell. According to information taken from the International Genealogy Index (I.G.I.), Jone was baptised on 2nd February 1599, in Marhamchurch, Cornwall England. On the 27th of December 1620 Jone married a Robte (Robet?) Sweet in Kilhampton, Cornwall, England.
A further search of the I.G.I., has failed to establish if Jone and Robte ever had children. It could be that they moved to another County or migrated overseas. There is of course the possibility that they never had children. If anyone has anymore information about Jone and Robte, or you feel you may be a descendant of any of theirs, please contact me at firstname.lastname@example.org.
