The paternal family name was, until the seventeenth century, O??Sullivan, deriving from a line of Irish gentry. From its less prosperous branches came Thomas Sullivan (1785-1838) who joined the British Army, serving during the Peninsular Wars and then in the detachment that guarded the fallen Napoleon on St. Helena, retiring with the rank of sergeant. One of his sons, also named Thomas (1805-1867), was trained as a musician. While an instructor at the Royal Military College at Sandhurst, in 1838 he married Mary (or Maria) Clementina Coghlan (1811-1882), a young teacher at a ladies?? seminary: though apparently with a Jewish element in her family background, she was primarily of Italian extraction, and a devout Catholic. Seeking better income, Thomas moved to London, where he took a job as clarinettist in a theater orchestra. As children came, the family eked out a precarious living until 1845, when he returned to Sandhurst as the bandmaster, building a reputation for wide playing and teaching competence (strings, woodwind, brass), he was able in 1857 to win a prestigious post on the faculty of the Military School of Music. His excellent musicianship, together with the diversity of his resources, provided an extraordinary opportunity for his son to become thoroughly acquainted with instruments and instrumental writing from an early age.

Half the Sullivans in England named a daughter "Mary"; I can't figure out which one is her in the LDS 1881. I haven't found a birthplace, either.
