The McPhersons were deeply patriotic when it came to WW1. All of the boys in the family enlisted and headed off to the Western Front (and, rather more remarkably, from whence they all returned alive, albeit not safe and sound). Werner had a rather distinguished war service, getting promoted to Lieutenant and winning a Military Cross for 'gallantry in action' when he cut down opposition trench wires with his machine gun while under heavy fire from the enemy. While he was away at the war, he met a young Canadian woman named Patricia M L H MacKay, and the two married in Warminster, Wiltshire in Jun 1918. He was a dashing young Australian-German-African-Scottish Apparently officer with a chestful of medals. It was summer in the northern hemisphere. The war really would be over by Christmas. I can imagine how exciting and romantic it all must have been.
Yes, they are from the branch of my family who are part African, and yes, Werner had just come back from Fiji so was on his more tanned end of the spectrum.
I have recently obtained Werner and Patricia's marriage certificate. Her full name was Patricia Maureen Liresay Henneker Rick, and she was born in Prince Albert to Francis Liresay Henneker Rick. She has previously been married (thus acquiring the surname MacKay).
