John Anstis, younger

He was educated at Westminster School and privately by Michael Maittaire.

In May of that year he was made genealogist of the newly created Order of the Bath.

This was a new office attached to that of the genealogist and first companion of the order; this creation was the work of his father, who had risen to the post of Garter Principal King of Arms.

In 1736 he was made a fellow of the Society of Antiquaries of London and he became the sole Garter King of Arms on his father's death in 1744.

The younger Anstis died a bachelor on 5 December 1754 at his house in Mortlake, Surrey, and was buried at Duloe, Cornwall.
