In 1963, the Gregg County Historical and Genealogical Society was founded with 70 charter members. From this group, the Board of Directors of the Gregg County Historical Foundation was established and chartered by the State of Texas on February 28, 1966.
On January 23, 1967, The Gregg County Historical Foundation was granted 501(c) (3) tax exemption by the IRS. A twenty-four-member board of directors governs the Gregg County Historical Foundation.
The Gregg County Historical Foundation had always hoped to have a permanent place to display its collection of historic Gregg County artifacts, documents and photographs. Ann Lacy Crain purchased the Everett Building and on May 27, 1979, donated it to the Foundation in loving memory of her parents, Rogers and Lawson Keener Lacy. Later that year, the building was entered in the National Register of Historic Places.
