with a Nicholas and Mary resident in Liverpool some years later.
Do you have them on any census?
Thanks Milliepede; I've just found an Irish record of Baptism for Henry, listing mother and father as Nicholas Slater and Mary Hefferen, the age is about right ... Nicholas (and Mary) later turn up on a Liverpool business directory, and Nicholas on the electoral role in the same area – profession, shoemaker. This also rings true, however the location is somewhat off. I'm now wondering if Liverpool was first port of call for those traveling from/to Ireland? Maybe this again keys into the traveling / transient aspect of things? Unsure...
