SIR THOMAS ASTON COFFIN, Baronet, son of William, Jr., was born at Boston, March 31, 1754. He graduated at Harvard College in 1772. He was for a long time Secretary to Sir Guy Carleton, by whose side he sat in the last boat which left Castle Garden on the evacuation of New York, 25th Nov., 1783. When Sir Guy Carleton became Lord Dorchester and Governor of Quebec, 1784, Coffin accompanied him and by his influence was appointed in 1804 Secretary and Comptroller of Accounts of Lower Canada. At another part of his life he was Commissary General in the British Army. He went to England and died in London in 1810, very wealthy. He was grandfather to Mrs. Bolton, wife of Col. Bolton, R. A., who took an active part in the Red River Expedition of 1870. WILLIAM COFFIN, the second son of William Coffin, Jr., was born in Boston, 1758, and died at Kingston, Canada, in 1804. EBENEZER COFFIN, the third son of William Coffin, Jr., was born at Boston, 1763, went to South Carolina where he acquired property as a merchant and planter and was the father of Thomas Aston Coffin of Charleston, South Carolina, whose descendants, with an hereditary instinct, distinguished themselves by their chivalrous devotion to a failing cause in the late Confederate war. NATHANIEL COFFIN, second eldest son of William, was born in Boston in 1725, graduated at Harvard College in 1744, received in 1750 an honorary degree at Yale. Brought up a merchant, he was early appointed King's Cashier of the Customs and acquired considerable property. He resided on the corner of Essex and Rainsford Lane, now Harrison avenue. The tide washed up to the garden wall. Near by in front, on what is now called Washington street, was the "Liberty Tree," where Captain Mackintosh and his "chickens," met to plan outrages upon loyal citizens. In August, 1767, a flagstaff was erected which went through and above it highest branches. A flag hoisted on this was the notice for the assembling of the "Sons of Liberty" for action. In 1775, his son Nathaniel, and his friends cut it down, much to the disgust of Mackintosh who was known as the "First Captain General of Liberty Tree." On the building occupying its site is a stone bas-relief of the tree with an inscription on it. Nathaniel Coffin held one of the most lucrative positions under the crown, his acquaintances and friends were naturally among the government officials and the better class of the community. He had much to lose if he severed from his fealty to the mother country and, banishment and confiscation would be the penalty, if the disunionists succeeded.
