Again, thank you very much Justin. I appreciate that the current Jewish communities (whether orthodox or not) may not be interested in this, but I thought that maybe enough would to be able to point me in a certain direction.
The fact of the matter is (silly though it sounds) that I haven't got any evidence of ancestors having lived in Portsea. What I have got are Jewish ancestors in the Midlands who had been born in Germany/Eastern Europe. Obviously, they couldn't have just landed there. Of the people that I can find they associated with/married etc, there seems to be a relatively large number born in Portsea. I've looked at their families & the same towns keep turning up;Portsea/Chatham/Canterbury/Gillingham/Gravesend. There seem to have been strong connections, which seems a bit silly when they're on opposite coasts. Only yesterday, I started looking for a family with the surname of Samuel. I wasn't looking for a particular family, but I had heard from a family member that there was supposed to be a link somewhere along the line around then. If you look at the Surname Search here, you will see that there are 2 posters with interests in the name Samuels specifically in those towns. From what I can gather, the pattern seems to be that they started from Portsea & then spread to Kent (sometimes by way of a short stop in London)
So I was wondering if my ancestors came in that way, too
