My information comes from the editor of the HAFS Journal (Peter Sherlock - Hungerford & Associated Familes Society)'s extraction of data from the Rev. Jackson's papers housed in England.John did marry Bridget Fettiplace.Their son Anthony did marry Bridget Shelley.They did have a son--John--who was born on 7 Aug 1566 at Great Bedwyn, Wiltshire, England.He married Mary Berkeley who was born in 1563.They had 7 or 8 children.(Stanley Hungerford in his Hungerford genealogy lists a child not mentioned by Rev. Jackson).I don't have a birth year for Bridget but in the sequence given by Rev. Jackson she was born after her sister Mary--who was born 1 Jul 1601 in Isleworth, London, England.I hope this helps.
