Offices Held


Lyon became a parliamentary candidate in 1766, when his brother John, the 7th Earl, in anticipation of the vast fortune accruing to him by his approaching marriage to Mary Bowes, a great heiress, embarked upon a campaign to wrest Forfarshire and Aberdeen Burghs from the Panmure interest. Lyon won the support of Administration and of the Bute party in Scotland. After a violent struggle Panmure was returned for the county and Lyon for the Burghs. Shortly afterwards the Strathmores and Panmures made a family compact to avoid future contests.

In the House Lyon was an obscure Member who voted consistently with Administration. After the death of Strathmore in 1776 and the marriage of Mary Bowes to Andrew Robinson Bowes, Lyon became deeply involved, as sole surviving uncle and one of the guardians of the Strathmore children, in financial and legal transactions to preserve for his wards their share of the Bowes fortune.1

He vacated his seat at the opening of the autumn session of 1778, and died 13 Sept. 1796.
