Chester,
And the best of luck to you...
A couple of snippets for you...
1)Catholic priests in Newcastle ( i.e St Mary's, St Andrew's.. )
in mid 1800s sometimes included extra bits of info on church marriage records.. such as names of groom and bride's mother's as well as fathers.. and sometimes ( if you ARE lucky) the Irish root County.
( St Patrick's, Felling... priest, at one stage was even recording county, parish and townland)
2) For whatever reasons, the Irish who came to Newcastle and north-east England, were from Irish counties Mayo, Sligo, Leitrim, Roscommon and Donegal. And some from Down and Antrim. But it is rare to see on Newcastle censuses, midland and southern Irish Counties recorded as birthplaces.
