Union Presbyterian Church was organized by John Warnock of East Alabama Presbytery in September 1843, with Pea River Presbyterian in Barbour County as its mother church. Its founders migrated from Scotland to Argura, North Carolina, and then to Union in Dale County during the 1820-1840's, calling the community Arguta. The church was housed in log or frame buildings in 1859, 1886, 1909, which burned in 1910, and from 1910 to 1915, and a Fellowship Hall was added in 1977. Founders included George B. Keahey, Elijah Keahey, William Keahey, Neil Munn, Norman Cameron, John Keahey, James Keahey, Sr., Hugh McDonald, Archibald McEachern, Dougald McFadden, John Munn, Sr., Nancy Campbell, Margaret Keahey, Sarah Keahey (1), Sarah Keahey (2), Mary Keahey, Eliza Keahey, Martha Keahey, Margaret McDonald, Catherine McEachern, Mary McFadden, Eliza McGill, Mary Munn, Catherine Munn, Ann McFadden, and Catherine McDonald.
