James Ryan's book is available at the GSV bookshop in Melbourne (Genealogical Society of Victoria). You can buy online. It's not cheap. I've also seen a couple of copies on Ebay. www.gsv.org.au and click on bookshop Cheers Beryl Beryl O'Gorman Greensborough Vic Australia
Also check for used book sites on-line. You'd be amazed at some of the prices from sellers and although they sometimes are not in "new" condition, they are fine. I buy used books a lot. Mary Anne
