Three placenames in the Canadian province of British Columbia were conferred in honour of the Birkenhead disaster by Hudson's Bay Company explorer Alexander Caulfield Anderson, a boyhood friend and cousin of Lt-Col. Seton of the 74th Regiment of Foot, on a traverse of uncharted country between the Fraser Canyon and the coastal Lower Mainland in 1846. Named after his cousin, Seton Lake cuts west through the Coast Mountains from the Fraser Canyon town of Lillooet, beyond which is its twin Anderson Lake.
