Matthias was Richard's secretary and was present to the first surrender of the Dutch New Amsterdam to the English.
In 1670, he bought land in present Plandome Manor, New York/Plandome, New York, and he is said to have named it for the Latin 'planus domus' meaning 'plain' or 'peaceful' home.
He was speaker of the General Assembly under Thomas Dongan in 1684 which guaranteed religious freedom to Christians.
He and his wife were buried in front of the manor home, although the exact spot is not now known because it was vandalized.
One of his children, William Nicoll, would sell the Plandome Manor in 1718, then over 1000 acres, and move to his own estate of 100 square miles (260 km2) on the Great South Bay in present-day Islip, New York.
