Kilkie as a family hasn't set the exploring world alight.
There are representatives of our Clan outside the British Isles but it is thin pickings. The countries with most connections outside the British Isles are Canada, South Africa, Zimbabwe and... that's about it. There are clearly people living across the world with Kilkie connections but the surname itself is rare. There are some Kilkie surnames in the United States but on closer inspection they all turn out to be Polish derivation from Kilkiewicz.
It seems our family has been largely satisfied with sailing doon the water between Ireland and Scotland with stopovers in other maritime bases (Liverpool, Gravesend...)
