I have heard that this book is a good resource tool. Could sks with access to a copy of this book, The Book of Irish Families Great & Small by Michael C. O'Laughlin, please look to see if there are any Osborne families listed in it? I am not sure what the author's criteria might be for an Irish Family. I suspect that my Osborne ancestors were Scots-Irish, and may only have been in Ireland for a couple of generations. Thought it might be best to see if they are even listed in this book before I bother the library to request it brought in on Inter-Library loan. Thank you very much. Betty Ann
