Linda, I was unable to track down your Isabelle/Belle Austin or Gleed, I searched the Australian Vital Records, checked out the [State of] New South Wales of which Sydney is the capital city and I also checked the North American Vital Records Index, in particular for Iowa and then for the whole of the U.S, alas no hits at all. I've sent a separate email to you with an attachment giving details of other people with the surname Gleed and Austin which were found, related directly to the Australian Search. I wish you well with your on-going research Don in Melbourne
