Brian Jnr has asked whether I am able to shed any light on your requests re Caspar. First, I am Brian Clayton Iselin; my father was Gordon Clayton Iselin - brother to your grandfather John Ronald Iselin. The "Ronald" in all of these names comes from the surname of the wife of Caspar Iselin - Anne Ronald, being the parents of the Caspar who started the family in Aust. On his (my great-grandfather) marriage certificate, his name is shown only as that of Caspar and is the same as his death certificate. My grandfather (your great-grandfather) was Caspar Ronald. In some documents, the Caspar is spelt Casper. Not sure which is correct. Another side to this is that your mother, Sandra, was a school chum of my wife and Brian Jnr's mother. I along with my dad attended her funeral. Hope this has been of some assistance. Regards Brian I.
