Bligh married Elizabeth Betham, daughter of a customs collector (stationed in Douglas, Isle of Man), on 4 February 1781. The wedding took place at nearby Onchan. The couple had eight children together: six daughters and twin sons (the boys died in infancy). The couple remained married until Elizabeth's death on 15 April 1812. A few days after the wedding, Bligh was appointed to serve on HMS Belle Poule as master (senior warrant officer responsible for navigation). Soon after this, in August 1781, he fought in the Battle of Dogger Bank under Admiral Parker, which won him his commission as a lieutenant. For the next 18 months, he was a lieutenant on various ships. He also fought with Lord Howe at Gibraltar in 1782.
