The Dallas Genealogical Society was founded in 1955 with the objective to educate, by creating, fostering, and maintaining interest in genealogy; to assist and support the genealogy section of the J. Erik Jonsson Central Library in Dallas, Texas; and to collect, preserve, copy, and index information relating to Dallas County and its early history.

The Dallas Journal, an annual publication, is an optional benefit of membership. The Journal contains genealogical and historical records, articles, and information pertaining to the cities and towns of Dallas County, the State of Texas, and local areas relating to Dallas County. Each volume is every-name indexed. The Dallas Journal continues the tradition of its predecessor, the Dallas Quarterly, published continuously from 1955 to 1994.

The DGS Newsletter, published since 1976, is also a benefit of membership. Ten issues are published each calendar year: January, February, March, April, May June/July, August, September, October, and November/December. Each issue contains information about DGS meetings and events, in addition to articles highlighting research tips, genealogical aids, library news, information about regional and national societies, news concerning the genealogical community, and member news. Queries are free for members; non-members pay $3.00 per query.

The Society year runs January through December. Program meetings are scheduled  every month with the December meeting being a social and annual awards banquet and business meeting.  DGS meetings are free and open to the public with the exception of the December awards banquet.

Meetings are usually held on fourth Mondays in the J. Erik Jonsson Library Auditorium. They begin at 6:00 p.m. with refreshments, 6:30 for a Question/Answer period, and the business/program meeting starts at 7:00 p.m. Programs feature educational and informative presentations on genealogical and historical topics. Meetings are over by 9:00 p.m. when the library closes. Guarded parking is available underneath the library at reduced rates.

DGS presents a variety of workshops designed to provide instruction in beginning and intermediate genealogy; genealogical research techniques; computer and internet technology; and genealogical writing and publishing skills.

The DGS website, http://www.dallasgenealogy.org, provides detailed information about events and how to access officers.
