Bishop of Lindsey, died c.700.
Brother of Edilhum (friend of Egbert and of Aldwin), abbot of Peartney (Lincs.) and also of abbess Ethelhild nearby, Ethelwin was consecrated by Theodore in 680. His diocese (roughly modern Lincolnshire) had formerly been part of Northumbria, but was later under the rule of kings of Mercia. Little is known of his achievements or even the place of his seat (see Herefrith), but Bede mentions him and his family. Feast: 3 May (or 29 June in Wilson's Martyrologe).
Bede, H.E., iii. 11, 27; Stanton, p. 193.
