He was the son of Townsend Mullins, the second son of Thomas Mullins, 1st Baron Ventry, and his second wife Christabella.
Mullins was commissioned a lieutenant in the 7th Regiment of Foot on 5 February 1807, and served with the regiment in the Peninsular War. He fought at Busaco and Albuera and was badly wounded at the latter. He purchased a captaincy on 13 August 1811.
He exchanged out of the 7th to take half-pay on 11 December 1817 and did not return to the Army.
On 16 February 1841 he assumed the surname of de Moleyns for himself and the other descendants of the 1st Baron Ventry. This was in token of Ventry"s claim to be descended of the medieval de Moleyns family of Burnham, Norfolk, which, however, has never been firmly established.
Lord Ventry died in 1868 at Burnham House, the family estate.
