Henry Hart (1566-1637) was an Anglo-Irish soldier and landowner of the Elizabethan and early Stuart eras.
Hart served in Ireland under Sir Henry Docwra during the Nine Years' War rising to the rank of Captain.
Following the Treaty of Mellifont he was appointed to command Culmore Fort an important strategic post close to Derry.
O'Doherty had served on the Crown's side during the recent war, and was a natural loyalist, but had been angered at his treatment by Docwra's replacement as Governor of Derry, George Paulet.
Several of Hart's former comrades also received land nearby which had been mapped out by the recent Bodley Survey.
