Hi Roger,
I'm late to this party but just read your note to Carl.
I lived in Fort McMurray for awhile. I remember being in a store there where a PA called for Mr Ibbotson to report to the office. I was shocked to find out it was you and not me!
Anyway, I grew up in Kingston (3 hours east of Toronto) so there's a lot of similarity here. I think we spoke once and didn't find any relatives in common.
But just in case, I now have a public family tree ("Ibbotson Family Tree") on ancenstry that you could look at.
Cheers,
Paul
PS After Fort Mac, I moved to Calgary, and then to Boulder, Colorado where I now live with my American wife. So this branch of Ibbotson has moved from England to Canada to USA in one generation!
