NOTE: Daniel's wife appears in some family trees as Mary Ann Mullins, b. 24 Mar 1891, d. 15 Jul 1977, Shirley, Van Buren, Arkansas; dau. of James Buel Mullins (1863–1905) and Josephine Hopson (1865–1893). In others she appears as Oda Alice Mullins, b. 29 Mar 1892, Lick Creek Township, Little River, Arkansas; d. 15 Jul 1977, Shirley, Van Buren, Arkansas; dau. of James Warren Mullins (1861–1953) and Josephine Elizabeth Love (1865–1907). In both cases, their date of marriage is given as 28 May 1905.
These two persons have obviously been conflated and sources have not yet been found to resolve the conflict. Further research is clearly needed.
