Margaret -
I grew up in Hendon, London, UK and there was a very
famous grocery store in Golders Green(neighbouring
suburb) called FLAX - every Sunday morning my Dad used
to go there and buy delicacies (smoked salmon, shmaltz
herring etc) for our Sunday breakfast.

Hopefully other genners will be able to put you in
touch with this family.
