Jane Elizabeth Leslie, 12th Countess of Rothes

Jane Elizabeth Leslie, 12th Countess of Rothes (5 May 1750 – 1810) was a Scottish noblewoman. She succeeded her brother in 1773 in the peerage and estates of Rothes, and effectually vindicated her right to the estates against the claim of her uncle, both in the Court of Session and the House of Lords. She was twice married, first in 1766, to George Raymond Evelyn, youngest son of William Evelyn Glanville of St Cleres, Kent, and secondly, in 1772, to Sir Lucas Pepys, Baronet, uncle of the first Earl of Cottenham. To both she had issue, and dying in 1810, was succeeded by the only surviving son of her first marriage, George William, 13th Earl of Rothes.
