[1] His family had a long association with the law: the first notable member of the family in Ireland was Sir Nicholas de Netterville, who served twice as High Sheriff of County Louth in the 1280s, and was appointed a judge of the Court of Common Pleas (Ireland) in 1301.
John's cousin and brother-in-law Thomas Netterville, who was clearly older than Luke (he died in 1528), and who married Alison's sister Elizabeth St. Lawrence, was a judge of the Court of King's Bench (Ireland).
[1] In 1555 Netterville was involved in litigation with yet another High Court judge, Walter Kerdiff, over the Dowth property.
In 1560 he sat on a commission to inquire into martial law in Meath, together with his colleague Richard Dillon, but he died later the same year.
[1] Some years after his death the Lord Deputy of Ireland, Sir Henry Sidney, described Luke in disparaging terms as a man who was "but second justice of one of the Benches...... of mean family.......born to nothing.
