I did a quick search on ancestry, and located trees there with a William Matthew Hobson:
BIRTH AUGUST 14, 1884 • Covington, Kenton, Kentucky, USA
DEATH MAY 25, 1939 • Sarasota County, Florida, USA
Shows him as the son of Matthew Galliene Hobson (1855-1924) and Maria Swindell (1852-1931). Maria is shown as the daughter of John Swindell. Matthew is shown as the son of William Hobson (1819-1886) and Jane Roper (1820-1863).
