In fact I am Anne Marie O'sughrue's grand daughter. However, I don't know the one you mention in your text. My grand ma's father was an irish man who came to Mauritius and married a mauritian national. From there, he went to work in South Africa but did not bring along his family. My grand ma's brother is Patrick O'sughrue who sent to New Zealand very long ago with his family.
If you have any more news, keep me posted.
