Went to the cemetery yesterday.
Went into the office to confirm where the graves are located and that process gleaned some additional informaton that you might not have.
Michael Bird died Jan 3 1895 not 1894 from inflammation of the bowels.
Mary died of pneumonia. In the records she is just recorded as Mrs. Bird. No first name or initial. Knew it was she because of the date of death which is March 11 1919.
They are buried in the old part of the cemetery and the graves were difficult to find - in fact, I didn't find them at all! However, tomorrow (Wednesday), I will be in that area again and will look for them.
I did come across 2 other Birds in that area though and took photos of their grave markers. They are for an Elizabeth Bird 1874 - 1940 and Marguerite 1918 - 1973 or 1978 (not sure because of moss and shadows).
If these are of interest to you, let me know and I will email the photos to you. (Please send me your email address).
