Re: Great Synagogue in London records #unitedkingdom
For marriages in many UK synagogues (including the Great Synagogue, London) from c.1880, you should try to get a copy of the Chief Rabbi's marriage authorization for the marriage, in addition to a copy of the (civil) GRO marriage certificate, There is an index of the Chief Rabbi's marriage authorizations (1880-1920), and details of how to obtain a copy, at https://www.theus.org.uk/category/find-marriage-record .
There are some delays at the moment due to the Covid-19 restrictions.
What information might I see on a marriage Authorisation?
The documents are part Hebrew and part English.
In the search box on web page above, type in the name Dinah Jacobs. There are several results with bride's of this name but only one with a spouse name of Simon SHERATSKI. You can then order the document.
This index was a collaboration between the Jewish Genealogical Society of Great Britain www.jgsgb.org.uk and the United Synagogue who hold these records.
For a better understanding of the terminology used in the Chief Rabbi's Marriage authorisation the see:
