The chapter is instrumental in administration of the Texas First Ladies' Gown Collection at Texas Woman's University. The collection was assembled by the Texas Society Daughters of the American Revolution (TXDAR) in 1940. The chapter serves as a liaison between TXDAR and Texas Woman's University.
The chapter has promoted the DAR Good Citizens program in area high schools since 1960. It also awards National Defense Good Citizenship medals. ROTC medals recognizing achievement are presented annually to high school and university students in Denton County.
The tradition of serving the ideals and purposes of the NSDAR, and strong participation in service to community, state, and nation, continue as hallmarks of the Benjamin Lyon Chapter.
