Family Group Records Collection

The Family Group Records Collection provides microfilmed copies of about 8 million family group records created by members of The Church of Jesus Christ of Latter-day Saints. The collection can help you survey research done previously by others, saving you time and giving you valuable information. While you should not assume the information to be completely accurate, you can use the information and sources provided on the family group records to guide you to original records. The collection is divided into two sections, the Archive Section and the Patron Section.

Archive Section
This section of the Family Group Records Collection contains five million family group records submitted by members of The Church of Jesus Christ of Latter-day Saints between 1942 and 1969. The records are only available on microfilm.

In the Archive Section, an asterisk (*) next to the name of the husband, wife, their parents, or their children indicates that this individual appears on another Archive Section family group record. An asterisk next to the name of a child's spouse indicates another spouse is specified on the back of the record.

Patron Section
Three million family group records were submitted to the Patron Section between 1926-1979. The purpose was to share genealogical information and identify others working on the same lines.Each section has some names that cannot be found in other filmings. The family group records often included a brief list of the sources used to compile the record. Some records also included biographical histories for the family members listed on the form.If members of the LDS Church participated in the Three Generation or Four Generation record submission programs, their original submissions would now be found on these microfilms.

Converting Old Microfilm Numbers to New Numbers
The data sources listed on these family group records often include old book and film numbers. There have been a number of old book and film numbers used by the Family History Library over the years to identify and label its book and microfilm collections. When microfilming began, a combination of letters and numbers was used to number the films. Later, a system of serial numbers with part numbers was used. Finally, a straight numbering system was used beginning with film number 000001. Each time, the existing films were renumbered. Today there are more than 2,400,000 microfilms in the library's collection.

In order to find a source on film, you may need to convert an old film number to a new film number. For instructions, see "Old film numbers."
