On the website page about Amble Manor House there is a reference from the Northern Catholic Calendar of the 1880s. It refers to the start of work on the building of the harbour in 1840 which brought to Amble a lot of Irish labourers. Many of them lodged in temporary wooden huts. Bet they didn't keep out the north easterly off the sea!
At the Northumberland Summer Assizes in 1843, two cases were heard linked to Amble. One was theft of money, by an Edward Laggin, from the Shanks family, innkeepers, for which he got 3 months hard labour, a previous offender. There is a different Laggin on the 1841 Irish list.
The second case was a death following a fight outside the Masons Arms "beer shop". The man who died was called Gilhespie, but not the one on the 1841 census. The accused, probably local, got 4 months hard labour.
I would imagine that Laggon and Gilhespie were both Irish, arriving after the census.
