After the completion of the E&N Railway in 1886, Captain C.E. Barkley, RN (retired) took to walking over to the little station at Hall's Crossing and handing his letters to the mail clerk on the train when it stopped there. Neighbours began asking the captain to take their letters also, and soon the postal authorities [supplied him with a mailbag.] When a post office was opened, Captain Barkley was appointed postmaster and the post office took the name of his house, Westholme, in which it was located. According to a grandson, Captain Barkley named his house Westholme because it was his 'home in the west' but it may have been the name of a family property in England. In 1909 Captain Barkley perished when a smaller house to which he had recently moved was consumed by fire. This Captain Barkley was, incidently, a grandson of Captain C.W. Barkley, who in 1787 discovered and named Barkley Sound.
