Begun in the Big Creek settlement area as the Pentecost Graveyard. This cemetery dates to at least 1841 with the burial of George s. Pentecost, an "Old 300" colonist. Also buried here are six of his children and their spouses, including son-in-law Samuel Pharr, an "Old 300" colonist on whose 1831 land grant the cemetery is located. Texas Revolution veterans George W. Pentecost and Andrew J. Beard, another son-in-law, and several Confederate veterans are buried here. Descendants of Beard married into the A. J. Brown family, thus giving the cemetery its present name.
