OK gone brain dead
His mother is called Mary not Ann - DOUH!
But on the 1841 census they are are in Bongate East Ward Westmoreland - and Margaret is listed so to confirm Marys maiden name it might be worth ordering her certificate
Strangely the older children aren't listed but Thomas was baptised 9.4.1826 Renwick, Cumberland
And it was Mary Law not Ann as I stated earlier
