Hi there...I was searching my name on google and came across your post. I'm descended from the Cara's in Penzance. The story my grandfather gave me was that all of the first-born son's were named Stephen and that the family fled from Portugal during the Spanish Inquisition and settled in Penzance (Redruth)...seemed to make sense considering my Great-Grandfather was Stephen (lived in Southern Ontario, fought in the Boer war and was a police officer) my Grandfather, Stephen Cyril Cara, my Dad, Stephen John Cara (Winnipeg), myself Stephen Harris (Calgary) and my son (Stephen Timothy Dale Cara), Abbotsford, BC. I've got most of the Canadian Family tree from the early 1900's intact...
