My name is Bianca Maria Ertl, my father's name was Barry Steven Ertl and my grandfather was Anton Ertl. I am trying to find any family that I might have. My dad mentioned we have family in Chicago, USA. But that is all I have been told. My grandfather was born in Hungary but moved to Australia and married my grandmother Mary-Elizabeth. My family have lived in Sydney Australia since before my dad was born in 1937. I would really like to find some family, both my father and grandfather have passed away and only my two brothers and nefew are left to carry on the name in Australia. Can anyone help?
