The International Genealogical Index (IGI) is one of the most useful tools available to the family historian working on the 16th to 19th century period. It has been compiled by the Genealogical Society of the Mormon Church as a tool to help their members trace their ancestors.
The IGI for England consists of entries from Church of England registers of baptisms and marriages from their commencement until around the end of the 19th century.
It is supplemented by material from Nonconformist registers, mainly for the period 1750-1840, and a number of other sources. The entries have been extracted on a county basis and put into alphabetical order of surname.
The Index therefore provides an important additional tool for anyone searching for a specific individual or trying to discover the areas in which a particular family name is to be found.
What we hold
The Index is available online at FamilySearch, which can be accessed though our public access computers at the Record Office.
It has also been printed on microfiche and there is a set of the 1992 edition for all the English counties in the searchroom. The Sussex IGI contains the registers of five sixths of the ancient parishes of West Sussex, and half of those of East Sussex.
