One of the things that I inherited from my grandmother Beatrice (Jordan) Dever was a Royal Canadian Artillery reunion booklet. She may have attended the event or collected it as her grandfather William Robert Jordan was honoured at the event. The reunion was held in Kingston, Ontario and was reported in the Kingston Whig-Standard on May 23, 1930.
William attended, placing a wreath on the R.C.H.A. memorial along with Mr. W.R. Abbott and Major General R.W. Rutherford.
The reunion booklet contains the programme, the committee members, a history of the regiment and photographs of members.
I have scanned the front page.

The Royal Artillery Museum has a write up about William Robert Jordan on their website.
