Orthodox prayer for dating
More than 20,000 live in Stamford Hill, in north-east London.
But it is a community, it seems, in which everybody knows everybody, and where a stranger is noticed.

Appalled at what they regarded as the laxity of the local synagogue, they established their own on the other side of the river.
In the face of this drift from tradition, the Haredi regarded themselves as the last redoubt of orthodoxy, taking sustenance from their rigid observance of the halacha - the body of ethical and ritual injunctions governing Jewish life.
There are now estimated to be around 1.3m Haredi worldwide, and according to a 2007 study by Dr Yaakov Wise at the University of Manchester, strictly-orthodox Jewry in Europe is expanding more rapidly than at any time since before the Second World War.
In Britain - home to the largest Haredi community in Europe - almost three out of every four Jewish births are in the Haredi community.
