I am searching for descendants of Donald and Margaret McDonald and children John, Allan, Angus, Catherine 'Kitty', Hugh/Ewan, and Alexander, who came to Australia in 1838/9 sailing from Tobermory, Isle of Mull. Donald and Margaret had a later child, Mary, born in Melbourne in 1840. After travelling to Sydney on the British King they sailed to Victoria on the John Barry. Hope someone can help, Irene Kerr
