George was born in Cottingham and Mary in Knottingley, W.Yorks. They were married in Hull in 1812.
No 'TUNDER' baptism records could be found in West Yorkshire around this time, though a number of 'TUNNER' and 'TURNER' records appear
in the Sheffield area (Ecclesfield / Laughton en le Morthen). It may be that Mary is the daughter of Thomas TUNNER and was baptised in 1787.
