You might be interested to know that there's a lot of information regarding norman online in the uk national archives. It seems he was interviewed by the security services at various points regarding his activities in the 1920s and the files are no longer classified.I came across them when i was searching for ewer.
I believe he was a well-known journalist for the daily herald?I can imagine what a surprise it was to find out.
The earliest i can go back to in my ewers is about 1700 when the first philemon ewer appeared in bursledon just outside southampton.They stayed there for about 120 years (3 generations of philemon and then a charles) as traders, timber merchants and shipbuilders (with a bit of smuggling i suspect). The second philemon was the famous one known as 'The Master shipbuilder' and left a considerable sum of money.The 3rd was called 'Captain' and married 3 times and who was 62 when he had charles.
Charles moved from bursledon in the 1820s and ended up in brighton as a coal merchant and lived until 1870.
I think he kept up shipbuilding on a small scale but he was the last. There has been a naval tradition since though.
Look forward to seeing your tree.I'd also be very interested to see anything you've got regarding the 18th and 17th centuries as that's the awkward bit and any info helps.
