In southwestern Fayette County, the Muldoon area was first settled in the 1830s after Father Miguel Muldoon acquired a Spanish Land Grant from Stephen F. Austin, and it continued to grow and attract settlers throughout the 19th century. In 1871, Jesse Sullivan, J.R. Allen, Duncan Carmichael, and J.T. Burleson, trustees for the Methodist Episcopal Church, purchased six acres from John Sauer for a church and burial ground. The first burial there was Dr. John B. Floyd (1842-1875), a doctor originally from St. Martins, New Brunswick, followed by James Carrel Bell (1820-1880), a Texas Revolutionary War veteran. Also buried there are Battle of San Jacinto veteran Simon Peter Ford (1816-1898), Duncan Carmichael (1827-1886), a Civil War veteran, and many other veterans from the Civil War onward, along with pioneer families, pastors, educators, and business leaders. Among the notable burials is James Chambers Coulson (1857-1909), an English immigrant, expert stonemason, and manager of the Muldoon rock quarries that supplied Muldoon Blue sandstone for many local landmarks, the Galveston Seawall and jetties, and buildings across Texas. At the center stands the Old Union Hill Baptist Church, moved there in the 1940s and used for funerals and meetings, and a cemetery association established in the 1940s has cared for the site as a tangible connection to the area's history.
