Sir Frederick George Milner was a Yorkshire landowner and Conservative politician who represented York and later Bassetlaw in Parliament. He succeeded his brother as seventh baronet on 14 April 1880 and was recorded in late nineteenth-century directories as lord of Acaster Selby Manor.

The contemporary directory evidence directly links him to the manor. The source does not establish whether his title arose by inheritance, purchase, settlement, or another conveyance.
