Interesting stuff.....I have come across a number of Ilands in my search on the web. There is a Harry Iland in Australia at Adelaide University but he is Polish background and does not appear to be any connection. I have also had some contact with Emily Iland. As far as I am aware the spelling is a change from Island, although I can understand the Hand.....my name is often mispelt that way. It is interesting to note the link with Cork as I was told when I was young that our family had come from there several generations ago. When would your Gt Gt Grandmother have lived?
