As mentioned by Randy Corston, the query regarding James Corston was incorrect, and I stand corrected. I have some new information regarding William A. Corston which may assist us to find any ancestors or any history of William A. Corston of Rendall Parish, Orkney. According to HBC Archives William entered service for the HBC on February 19, 1836 and sailed to Moose Factory on the Prince of Wales June 21 - 27, 1836. there is no indication of a birth date, however he died April 6, 1898.
