Andrew was elected bishop in a disputed election held on 3 February 1261, when Andrew won a minority of the votes of the cathedral chapter, and William de Taunton won the majority. Andrew held the office of Prior of Winchester at the time of the disputed election.[1] He probably was forced into the office of prior by the previous bishop of Winchester, Aymer de Valence about 1255. He received a dispensation for his illegitimacy on 10 December 1258 from Pope Alexander IV and became a papal chaplain in 1259.[2] The election to bishop of both men was quashed by the pope before 22 June 1262,[1] and Andrew attempted to recover the office of prior, but was unsuccessful. He died sometime after 8 April 1278 when he was once more unsuccessful in regaining the priorate.[2]
