Drumsloe is known as early as 1609 AD when it was known as Dromslo, a name that may be from Druim Sluagh meaning ridge of the hosts.[2] The Griffith's Valuation of 1863 indicates a school was located in Drumsloe.
Significant landmarks include drumsloe lough, where illegal distillery on Drumsloe Island was operated for some time in the early 19th century.[3]
