Lori,
I did your look up at the Barrie Public Library on the weekend and I'm afraid to report that there were no notices in the Barrie Examiner or Northern Advance for you John Gilrie/Gilree.
Here is what I did find:
Esther Gilree, see Peter Wm Scott
Maggie Gilree, see W.H. McLachlan
Jas. A. Gilrie, m. Harriet (Hattie) Johnson, both of Barrie, March 14, 1872 at Toronto
Harriet Gilrie, d. 23 July 1889
Violet May Gilrie, d. 20 Apr 1891, age 16
If you think any of these are yours let me know and I can grab them on my next visit.
Joanna
