Laurence of Lincoln, master, was a canon and official of the archbishop of York by 17 October 1237 and held the prebend of Wetang. He was later archdeacon of York, appearing first in February 1241. He was granted a papal dispensation to hold an additional benefice on 24 June 1245. In that year, he was murdered by a knight, Hugh de Tywa, brother of Sir John de Tywa. His will was proved in 16 January 1248 and called for the foundation of a chantry at altar of St Laurence in Minster.
