The purpose of the Williamson County Genealogical Society is to create and foster an interest in genealogy and to aid individuals in their genealogical research and compiling their family histories. To further this aim, the Society is dedicated to: gathering and preserving genealogical and historical data; maintaining a genealogical research library through purchases, contributions, donations and exchanges of books, periodicals, microfilm and electronic media; publishing a monthly newsletter titled "The Roundup" and a quarterly periodical titled The Chisholm Trail; and by offering educational opportunities in the form of lectures, classes, and seminars.
