Hertford is just north of London. It would appear that as early as 1515 the surname Jones [spelled Joones in this case] was already active in the legal records.
"Edward Joones" is the name. He is listed as "of London, brewer". [bundle 421/ no. 52 ] His case involves a "John Ayleworth of Bristol". The reason is "detention of deeds, messuage & land in Ridge". London and Bristol were key sea ports for trade through out the rising commerical network. Why the case is recorded in Hertford is unclear, but I would guess that Edward Joones' family must be from this county. A "brewer" indeed he is...cheers.
