And the answer: yes. A LOT.
So East London and North London with a York outlier.
If you know your London (and York) history, then that says one thing is likely: Jewish families.
1) Somewhere to start looking for marriages/births
2) An origin for what looks like some classic chain migration - Russia.
1) That'll give us more recent records with location markers, nearby
2) It'll help us find TRADES
3) Because the likeliest reason for two names on a shop, of that vintage, is a MARRIAGE LINK.
BUT...
Remember what we learned about our Goldbarts? They're RUSSIAN Jews.
So let's assume the Dollows arrived and did what Jews have often found themselves doing for safety: changed their name
But I'd say it's a solid punt, and if nothing else we've just discovered two interesting London lives.
