Sir Patrick Barnewall or Barnwall (died 1622), was the eldest son of Sir Christopher Barnewall of Turvey House, Grace Dieu Abbey, and Fieldston. Christopher in turn was the son of the elder Sir Patrick Barnewall, who in 1534 was made Serjeant-at-law (Ireland) and Solicitor-General for Ireland, and in 1550 became Master of the Rolls in Ireland. Patrick's mother was Marion Sherle, daughter of Richard Sherle of Shallon, County Meath: after his father's death, she remarried the prominent judge Sir Lucas Dillon. She died in 1607.

After the death of Mary's eldest brother Henry Bagenal at the Battle of the Yellow Ford in 1598, Patrick was appointed guardian of his children. Mary Barnewall and her sister Mabel are major characters in the play Making History by Brian Friel. Early career Barnewall began to attend the Inns of Court in London, one 'of the evident tokens of loyalty' which led Elizabeth I in November 1582 to make him a new lease of certain lands without fine for sixty years.
