George William, "the 7th Earl of Carlisle" served for 17 years as an MP until defeated in 1841, after which he toured North America for a year. Twice Lord Lieutenant of Ireland, he was made a Knight of the Garter in 1855.

*George William never married & was succeeded by his brother William, "the 8th Earl of Carlisle." However, between 1864 to 1880, the 7th Earl's younger brother (Admiral Edward Howard) lived in Castle Howard, owing to the 8th Earl's mental infirmity! Inshort, William "the 8th Earl of Carlisle" was basically nuts!
