About Thomas Henderson, Lord Chesters
"Sir Thomas Henderson, of Chesters - Son of Dr Edward Henryson also a senator. He was one of the commissaries of Edinburgh prior to 1600, and acted as advocate depute in 1606, in certain processes of forfeiture before the Parliament. He was knighted and admitted an Ordinary Lord on the 6th June 1622, in place of Sir Lewis Craig of Wrightslands. This promotion was the reward of his services to the Episcopalian cause, and was gratefully acknowledged by Spotswood, the primate, in a letter which is subjoined. In 1633 he was appointed one of the Commissioners for revising the laws and collecting local customs. He resigned his seat in the beginning of 1637, and obtained a letter from the king, dated the 2d February that year, whereby his Majesty, upon the narrative that the Ordinary Senators of our College of Justice who had worthily behaved themselves in that charge, and thereafter by age and infirmity finding themselves unable to discharge that service any longer, demitted the same in the hands of our royal predecessors, were still allowed to enjoy the privileges of the house during their lifetime, ordered that Sir Thomas should retain and enjoy during his life, the title and privileges due to his place. His possession of these was however short, as he died on the 3d February 1638."
