I know a few, went to school with them ie 6th form. The area i live in Gantshill whish is about 10 mins from ilford used to have a very high population of Jewish people around. My next door neighbour, old lady that she was...was jewish but sadly passed away a few yrs ago.
15 yrs ago when i first moved here, there were quite a few jews around...now there isnt so much...they more or less moved out of the area...think most of them went over to golders green or north london side if i recall. Still have the jewish place of worship in Ilford, just down the road from me.
