Aboriginal man who lived on the southern side of Botany Bay and was sometimes called the 'Chief of Port Hacking'. His English name was based on the name of convict transport and whaling ship, the William and Ann, and he was referred to in the press by various versions of this including Willimannan, Wil-lam-an-nan, Wilhamanan among many others. In the 1820s, he worked as an armed police tracker as well as on whaling ships. In 1838 he was stung by a catfish while fishing with Europeans in Darling Harbour and taken to the General Hospital where his right arm was eventually amputated. He died of exposure in Hyde Park in 1844.
