Background
He was born in Dublin, son of William and Anna Tisdall, who came from Carrickfergus.
He was born in Dublin, son of William and Anna Tisdall, who came from Carrickfergus.
He entered the University of Dublin in 1687, became a scholar of the University in 1692, a fellow of the University in 1696, and doctor of divinity in 1707. He became vicar of Kerry and of Ruavan, County Antrim in 1706, vicar of Drumcree, County Armagh, in 1711, and vicar of Belfast in 1712. Swift admired both Tisdall"s theological views and his style of preaching.
Tisdall wrote to Swift in 1704 announcing that he intended to propose to Stella, and Swift wrote in reply to dissuade him.
Swift"s letter was courteous enough in tonehe stressed the practical difficulties of such a marriage, since Tisdall was not a rich man, and the Church had not yet found him a salaried position - but he privately expressed his disgust at Tisdall as an "interloper", and their friendship cooled official lieutenant is not entirely clear whether or not Tisdall proposed to Stella, but if he did she certainly refused.
Stella, it is clear, would marry Swift or no-one: whether as she apparently claimed they were secretly married in 1716 remains a matter of intense debate. After Stella"s death in 1728 the two men were reconciled, and Tisdall witnessed Swift"s will.
Tisdall died on 8 June 1735.
Tisdall in 1706 married Eleanor Morgan of the prominent County Sligo landowning family whose seat was at Cottlestown, and had a son, also called William. Philip Tisdall, later as Attorney General for Ireland to be a very powerful figure in the Irish administration, was a cousin of the next generation. Tisdall was known for his pamphlets on religious controversies, of which the best known was Conduct of the Dissenters in Ireland (1712).
He joked that this pamphlet saved Ireland as surely as Swift"s The Conduct of the Allies saved England.
Swift was apparently not amused. He published little after 1715, apparently feeling that the political climate was unreceptive to his opinions.
