My grandmother was very adamant and proud that she was a 1st cousin of David McCallum (Glasgow Born Actor - as a young man, Illya Kuryakin in "The Man from Uncle"). Years ago I looked at his bio, and did not see a connection. I even wrote to him via his Secretary, just in case, got a really nice letter back, but no relation.
A couple of years later I obtained a marriage certficate for my GGFather, on it one of the witnesses was his sister - Catherine Watson, the other witness, her husband - David McCallum!! Further research showed that Catherine Watson and David McCallum had a son, another David McCallum, born Glasgow around the same time as "the" David McCallum" A bit like Reayboy's post!!
But talking about usually a grain of truth somewhere in the old stories handed down, another cousin of mine told me that a great-grandfather had been a Ships Captain, and our Grandfather had travelled the world with him as a child. . A couple of years later I found that my GGF, the said ships captain, had been an Accountant, a Manager, and a Passenger Agent for CPR. Worked in London, then Boston (where my Grandfather was born) then Montreal.
On his marriage certificate, my grandfather is listed as a ships steward!! So, at the very least, they were actually involved with shipping - so there's that grain of truth!!
