The Bayntun-Sandys Baronetcy, of Miserden Castle in the County of Gloucester and of Chadlington Hall in the County of Oxford, was a title in the Baronetage of the United Kingdom.
[1][2] He had been born Edwin or Edwyn Sandys, but had assumed the additional surname of Bayntun.
[4] The change was in order to inherit from the will of William Bayntun (1717–1785), a lawyer of Gray's Inn and husband of his first cousin once removed, Catherine Sandys (1737–1804).
[5][6] Edwin Sandys married, in 1799, Agnes Cornish Allen (1778-1846), daughter of Michael Allen of Coleridge House, Stokenham near Kingsbridge, Devon.
Their elder son, Edwin Windsor Bayntun-Sandys (1801–38), was knighted in 1825 but predeceased his father in 1838,[7] as did his only brother Myles (or Miles) Allen Bayntun-Sandys (1812–1813).
