Born in Milk Street in London, on 7 February 1478, Thomas More was the son of Sir John More, a successful lawyer and later judge, and his wife Agnes (née Graunger). More was educated at St Anthony's School, then considered one of London's finest schools. From 1490 to 1492, More served John Morton, the Archbishop of Canterbury and Lord Chancellor of England as a household page.
Morton enthusiastically supported the "New Learning" (now called the Renaissance), and thought highly of the young More. Believing that More had great potential, Morton nominated him for a place at Oxford University (either in St. Mary's Hall or Canterbury College).[8]:38 Both Canterbury College and St Mary’s Hall have since disappeared; Christ Church College grew over Canterbury's site, and Oriel College over the former St Mary’s.
More began his studies at Oxford in 1492, and received a classical education. Studying under Thomas Linacre and William Grocyn, he became proficient in both Greek and Latin. More left Oxford after only two years – at his father's insistence - to begin legal training in London at New Inn, one of the Inns of Chancery.[7]:xvii[9] In 1496, More became a student at Lincoln’s Inn, one of the Inns of Court, where he remained until 1502, when he was called to the Bar
