How to Use the Indexes to Marriage Registrations (RG 80-7)


The Indexes to Marriages (RG 80-7) are computerized print-outs that were created by the Office of the Registrar General in the 1960's to replace a manual indexing system. They index marriage registrations and delayed registrations. To use these indexes you need to know the name of the people whose marriage you are tracing and the year the marriage took place.

The registrations are indexed by both the surname of the groom and the maiden name of the bride. If the bride had been previously married, her married name is indexed rather than her maiden name.

The Marriage Indexes for 1873-1910 are arranged:

1. First, by surname initial
2. Then, by year of the marriage
3. Lastly, alphabetically by the full name.

The Marriage Indexes for 1911 and after are arranged:

1. First, by year of the marriage
2. Then, alphabetically by the full name.
