He also presented a marble fount to one of the churches, and gave the land on which the new one was built." It is also said of him that he always boarded the unmarried ministers of the parish free of expense.  He was a Burgess from Middlesex Co., in 1749; of the King's Council, and its President, in 1750; and Receiver-General of the Colony from 1754 to 1776.  He left large estates in Virginia, "Lanesville," in King and Queen, "Buckingham House," in Middlesex, "Moss Neck," in Spott-sylvania, and other estates in Virginia; he m.

III--Colonial Councillors of State  Name: Richard Corbin of "Buckingham House," and "Corbin Hall," Middlesex county, and "Laneville," King and Queen county, was the son of Col. Gawin Corbin of the same place, and was for many years one of the most eminent and influential men of the colony of Virginia.  He was educated in William and Mary College and probably also in England, and early in life was appointed a justice in Middlesex county.  He represented this county in the house of burgesses in 1751 (and doubtless for several years before) and was, during that session of the assembly, appointed to the council, in which body he sat until the revolution.  Col. Corbin was appointed receiver general of Virginia about 1754, an office which he also held until the close of the colonial regime.  Through his influence George Washington received his first military commission.  In 1754, young Washington wrote to Col. Corbin asking a commission in the military service of the colony.  A major's commission was obtained and sent him with the following letter:  Dear George:  I enclose your commission. God prosper you with it.  Your Friend, RICHARD CORBIN.  Col. Corbin rendered efficient service in council during the French and Indian war, and received, along with Washington, William Fairfax, Gov. Dinwiddie and some others, a medal, as a sign of royal approbation.  In April, 1775, Gov. Dinwiddie secretly removed the powder from the magazine in Williamsburg, and by so doing gave a great impetus to the revolutionary spirit in Virginia. Throughout the colony meetings were held, and armed volunteers offered their services to redress the indignity done to Virginia by the governor.  The Hanover county committee of safety resolved to take immediate steps to recover the powder or to make reprisal for it. "Ensign Parke Goodall with sixteen men, was detached into King and Queen county to Laneville, on the Mattapony, the seat of Richard Corbin, the King's deputy receiver general, to demand of him the estimated value, and in case of refusal to make him a prisoner.  The detachment reached Laneville about midnight and a guard was stationed around the house.  At daybreak, Mrs. Corbin assured Goodall that the King's money was never left there, but at Williamsburg and that Col. Corbin was then in that town.  Henry, meanwhile, with 150 men, had marched on Williamsburg and halted at Doncastle's Ordinary to wait for Goodall.  There was intense excitement at the capital, Dunmore made preparation for defence, and even the patriots there were alarmed at the approaching storm.  Carter Braxton, Col. Corbin's son-in-law, interfered and obtained from the latter a bill of exchange for £330, the estimated value of the powder, which Henry promised to hold subject to the order for a general convention.  In this way the disturbance in the country was temporarily allayed.  It was subsequently ascertained that the powder was worth only about £112, and the residue of the money was returned to the receiver general.  Though it was well known that Col. Corbin's sympathies and belief were with England in the contest, yet when he retired at the outbreak of the war, and lived quietly in the country, he received no molestation from the new government.  Doubtless his high character and past services had much to do with this, but it may also have been due to his feeble health." There is an interesting reference to Col. Corbin in a letter written by his son, Francis P. Corbin, in 1813.  In it is stated that the King actually sent a commission to Col. Corbin, appointing him governor of Virginia after the abdication of Lord Dunmore, but that it came too late and that Corbin prudently hid it in a secret drawer of his escretoire.  No record has been found of the death of Richard Corbin, but it must have been in, or subsequent to, 1787.
