5th generation Australian (not a convict, my family has lived in South Australia since the 1830's).
Before that, mum's family is from Cornwall (a little place called Spargo - the vanity was hereditary).
Dad's family were Spanish pirates in the 1600's, who were so notorious they had to move to Ireland and change their surname so no one would know where they were -ooooh-
So.. Irish/English/Spanish, looking like a typical Australian.
