John Orde, younger brother of the first Baron Bolton, was an Admiral in the Royal Navy and was created a baronet, of Morpeth in the County of Northumberland, in 1790.

The sixth Duke died without male heirs in 1794 when the dukedom became extinct and the Bolton estates passed to Thomas Orde in right of his wife.

His grandson, the fifth Baron, sat as a Conservative Member of Parliament for Richmond and served as Lord Lieutenant of the North Riding of Yorkshire.
