The Earldom of Kellie was united with the Earldom of Mar in 1835, when the 26th Earl of Mar became also the 11th Earl of Kellie. At the death of that Earl in 1866, the Earldom of Kellie and the family's estates passed to Walter Erskine, the cousin of the late Earl, and his heir-male. Meanwhile, it was assumed that the Earldom of Mar passed to John Francis Goodeve, the late Earl's nephew, and his heir-general. Goodeve changed his name to Goodeve Erskine; his claim was agreed upon by most individuals. He even participated in the election of representative peers for the Peerage of Scotland.
