Linda, You say the Richardsons were living at/on Birkhead Moor when they baptised William at Netherwitton. A small community/farm called Birkheads lay within the Township, Ritton Coltpark, which lay within the Parish of Netherwitton. A small community/farm called Colt Park/Coltpark lay in that same Township, Ritton Coltpark, within Netherwitton Parish. Lists/databases of communities/farms etc within the Parish of Netherwitton show no place called Cold Park. Ditto for all of Northumberland ! Armstrong's map of 1769 shows Birk Heads very close to Colt Park- no sign of any Cold Park in vicinty.! Michael
