Thanks for the interest re. Rourkes. I have traced the family back to 1841. The census shows the family living in Liverpool St, Prescot, Eccleston together with other families born in Ireland. The family comprises of James & Margaret and the children, Michael,William,Maria,Margaret,Catherine,Julia. Julia has an indicated age of 2 months and the birth took place in Ireland. This is the problem. The census figures say 'Ireland'. If this is true, then the family have just arrived from Ireland, but from where? I asked the original question because I thought it was possible that the 'Rourkes' came from a particular part of Ireland. Inconveniently
they don't!
James, one of the children above, was 16years old in 1841. I have a marriage certificate showing that he married Mary Kearns in 1852 in the Lowe House Chapel according to Roman Catholic rites. Thanks again for your tips.
