“Wickshire” could only refer to one thing: an old tract laid out in 1913, due south of this street, called Warwickshire Heights (see Newton Street about the Warwickshire, UK-born landowner). Wickshire Avenue wasn’t named until much later – 1957, to be precise – but its developers cited Warwickshire Heights on their tract map, so they obviously knew their local history. Why did said developers cut the “War” from the name? Maybe they were pacifists? All joking aside, my guess is that “Warwickshire” was simply too long to fit on a street sign. There definitely are no “Wickshires” in Great Britain.
