Penrhyn was born Edward Leycester, the son of the Rev. Oswald Leycester (later Oswald Penrhyn), of Stoke on Tern, Shropshire, by his marriage to Mary, a daughter of Mr P. Johnson, of Timperley, Cheshire. He assumed the name of Penrhyn in lieu of Leycester, in accordance with the will of Baroness Penrhyn in 1817. In 1823 Penrhyn was "of East Sheen".
