My attention has been brought to this discussion by Cara, so my thanks to her.
Kim Mettem in Perth, we are cousins and I would like you to get in touch. If you google "julia villiers", you should be able to find a thread at another forum that includes my address.
I have never heard any reference (other than speculation) to our George Halpins being connected to Captain Robert Halpin or to a Nicholas or John Halpin, or to Wicklow but I am always willing to learn. I would be most interested to learn more of Raymond's information and sources on this if he would care to do so. George Halpin senior, born circa 1779, wife Elizabeth, is as far back as I have been able to go. If, as Raymond suggests, George was secretive about his relations, that may explain why.
It may also explain why, if these were his family, there is absolutely no history of their names John, Nicholas, Robert, Edmund, etc in the descendants of George Halpin.
But George does appear to have had a son named Oswald and I would like to know where that relates to - possibly his wife's family.
