Hi 'isambard' and welcome to this site from the Cornish Terrier.
My guess is that you are related to ANDREW DUNSTAN QUICK who married PHILIPPA TREWHELLA in Montreal in 1921.
This being the case means that you and I are related a little more closely than mere friends on a Genealogy Help Forum.
I had corresponce with Dr William Andrew Quick many years ago and have his letter in my files here (somewhere in a box at the moment).
I would like to continue this further and help both you and myself find more to fill in the gaps.
It may be preferable to have some discussion via PM (or email) regarding my earlier correspondence with Dr Quick so as to not clutter this forum with unnecessary discussion.
I am not certain without doing some checking - but I believe we may also have a South African connection here.
Dates and information need to be checked - but, all being as it should, I think I have a copy of a photograph of John Trewhella Quick who was the brother to William Andrew Quick.
John T was born in 1927 but I need to check further details and find the copy of the photo before I go much further.
I have it on file in my computer but ned to find it. Sorry if that sounds a little odd but I have just recently moved house and my organisation of everything is completely 'out of whack'.
Guess we will be 'talking' soon.
Ian
