St. Ebba, or Tabbs, Virgin and Abbess
SHE was sister to St. Oswald and Oswi, kings of the Northumbers, and, assisted by the liberality of the latter, founded a nunnery upon the Darwent, in the bishopric of Durham, called from her Ebchester; also a double separate monastery at Coldingham in the marshes, now in Scotland, below Berwick. This latter house of nuns she governed herself till she was called to eternal bliss in 683. See Bede, l. 4, c. 19, 25, and Harpsfield.
