Question: I have a patch from WWI from my great-grandmother's sewing box. I know it would be from Canada, and I assume it belongs to a relative. Can you identify a patch that has a rectangle green, with a red circle above it? Answer: The patch in question sounds like the 4th Canadian Division - 54th Battalion emblem.
