The map below gives you an overall view of the geographical distribution of
Joslin events in Essex
in England and Wales since 1837.

An event is a Birth a Death or a Marriage that has been registered
since the commencement of civil registrations in July 1837
in total we have around 22,000 Joslin events in the UK alone.
It is very obvious that two distinct areas of Joslin’s have been popular in England;
one in Devon and the other in Essex, London, Hertfordshire and South Suffolk.
The registration district with the most events was Chelmsford.
In total some 6000 Joslin events took place in Essex in various registration districts,
1800 in Chelmsford (including the Maldon registration district),
1100 in Braintree (including the Witham and Halstead registration districts), and
900 in Colchester (including the Lexden and Tendring registration districts).
