John Jones was a busy fellow during his days as a merchant of Southampton. He is also listed in Middlesex which would make sense as a merchant starting around 1558. His cases are found in [bundle 26/ no. 119], [bundle 86/ no. 29], and [bundle 187/ no. 56]. The cases are indexed: John Jones of Southampton, merchant. Interestingly, the Isle of Wight just off the coast, did not seem to have anyone with the surname JONES involved in their legal records during this period of study. [Roughly 1300 - 1700.] I would suspect that the merchants of London used the ports of Hampshire on many occasions.
