Usage Tips

"The International Genealogical Index (IGI) is a computer file created by The Church of Jesus Christ of Latter-day Saints. It was first published in 1973 and continued to grow through December 2008. It contains several hundred million entries, each recording one event, such as a birth, baptism (christening), marriage, or death.

Information in the IGI came from two sources:

1. Some of the entries in the IGI were indexed by the genealogical community from collections of vital and church records (approx. 460 million names). Indexed records are valuable sources of primary information. Unfortunately, attempts to prevent duplication resulted in the exclusion of some indexed records.

2. Some of the information in the IGI was contributed by members of the Church about their ancestors (approx. 430 million names). The quality of this information varies. Duplicate entries and inconsistent information are common. Always verify contributed entries against sources of primary information."
