 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 .
