The eponymous William is William Gourlay of Kincraig, who lived in the nineteenth century. ‘The inhabitants (of ELI) are principally congregated in Earlsferry, Elie, Liberty and Williamsburgh ...’ (Millar 1895 ii, 4). In 1891 Liberty and Williamsburgh were incorporated into ELI.
Rottenrow, ‘rat-infested row (of houses)’, appears to be the earlier name of this settlement, and probably explains the change to the more gentrified Williamsburgh.
