An appointment as Chaplain to King George II in 1756 led Robert Fowler to a seat as Dean and Prebendary of Westminster Abbey from 1765 to 1771.
The Irish Privy Council was a private committee of King George III's closest advisors to give confidential advice on affairs of state.
In William Domville Handcock's book, The History and Antiquities of Tallaght in the County of Dublin (published 1877), the writer recounts a brief detail of a Vestry meeting in 1783.
This account would support why his parishioners and contemporaries thought him a kind, courteous and affable man—as he was also described in Samuel Burdy's The Life of Philip Skelton (published 1792).
In 1782 he was one of 12 Spiritual Peers in the Irish House of Lords who opposed the Bill for the relief of Dissenters on the grounds that it would promote clandestine & improvident marriages.
It would seem from the evidence that in spite of Philip Skelton's commendation of Fowler's great regard for religion, his main interests were in family, gardens and with little reverence for antiquities.
Martial law was imposed over most of the country, and its unrelenting force put the United Irish organization under severe pressure to act before it was too late.
Due to ill health, Archbishop Fowler lived the remaining two years of his life at Bassingbourne Hall in Takeley, Essex, England, a seat which he rented from Sir Peter Parker, 1st Baronet (who himself purchased the estate from Francis Bernard, 1st Earl of Bandon).
Until fairly recently, the exact burial place of such a man of importance at Holy Trinity Church had presented something of a mystery, as there was no memorial, tomb, or tablet of any kind to him.
The discovery of a vault filled in during the Victorian restoration has solved this mystery, and it is now known that Robert Fowler, Archbishop of Dublin, is buried under the Chancel (or Altar) of the Holy Trinity Church, Takeley.
Bassingbourne Hall, the great house built by William Towse circa 1580, and the last residence of Archbishop Fowler, was demolished in 1813 according to the will of the owner, Sir Peter Parker.
