I can only find the one in Leonard Gate in 1851, shoe maker,
The (T) in Tynemouth, Christ Church records ,do mark the person as dying from Typhoid as there was a epidemic there in the 1830s,
I have googled to see if there was an out break in Lancaster ,I haven't found any thing to say there was ,but I suppose it could be a contained case with in the family, a death certificate would say cause of death ,if the poster decided to pursue this further,
