Pallot's Marriage Index for England: 1780 - 1837. The original paper slip index, from which this database was created, is owned by The Institute of Heraldic and Genealogical Studies, Canterbury.
Pallot's Index to Marriages covers all but two of the 103 parishes in the old City of London, England. Information available includes: spouses names, marriage date and parish of marriage. The dates span the time from 1780 to the onset of General Registration in 1837.
The more than 1.5 million marriage entries come mainly from London and Middlesex, but also include entries from 2500 parishes in 38 counties outside of London-many not available in other sources. Also included are several records from counties in Wales.
The Derbyshire marriages (and a few other stray references) are contained in a PDF file. Download HERE
