The best place to start your search would probably be the Suffolk Record Office in Gateacre Road, Ipswich
http://www.suffolk.gov.uk/sro. You could also try searching the Newspaper Archives
http://www.britishnewspaperarchive.co.uk/ Ipswich Journal might be a good starting point for anything relating to the family in Suffolk.
Enjoy your visit
