A couple of further pieces of information on the Pembrokes... One of my grandmother's uncles, John, emigrated to Australia, and one of her brothers, Joseph, followed in the 1920's. I also just discovered that another uncle, James, emigrated to Canada (where I have now lived for many years) in the 1860's. That was never previously known in my family. There were very few Pembrokes in Wexford - in fact all of them are probably descended from Michael (c.1806 - 1880). There are quite a few more in Kilkenny and Kerry so that is likely where Michael hailed from, though I have yet to make that link. And I had a couple of very interesting finds on a recent trip to Ireland.
