Southampton is certainly a possibility except of course I've just realised that I was getting Suffolk and Sussex muddled up. Southampton would have been some distance from Suffolk but looking at my atlas I see that Burgh is a tiny village not far from Woodbridge and the port of Felixstowe. Perhaps Thomas Netherwood was a sailor? I would imagine it would have been easier to get from Southampton to Woodbridge by sea than land in the 1600s. Debbie Kennett
