Wilfred Rokeby was the longtime proprietor of the post office in Rosenfeld, Manitoba, Canada. As might be expected, he was acquainted with the McGregor family during and after the war. He shared many of his customers' frustrations with U.S. occupation. In 1917, he shared gossip with Arthur McGregor that U.S. Major Hannebrink, the officer who ordered the execution of McGregor's son Alex, had a mistress on the outskirts of town. After McGregor killed Hannebrink, both men became more circumspect with each other, until McGregor's own death.
