Francis Marsh, Archbishop of Dublin, and Mary, daughter of Bishop Jeremy Taylor.
[citation needed] Marsh originally wanted to engage in farming or in becoming a part of the clergy, before acquiring a career in surgery.
After accidentally losing his right forefinger, injured during an operational procedure he was performing, he left his career in surgery.
[citation needed] He died suddenly at his residence in Merrion Square, Dublin, and was buried in Mount Jerome Cemetery.
Marsh had married Anne (d. 1846), daughter of Thomas Crowe, of Ennis, county Clare, and widow of William Arthur; their son, Henry, a Major in the 3rd Dragoon Guards, (born 3 April 1821, died unmarried 27 May 1868), succeeded his father as the 2nd Baronet according to some sources.
