A few things ...
1. Michael Bird was listed as being born in Ireland. Not sure if you knew that or not.
2. I went to the cemetery today and tried to find the 2 graves and had absolutely no luck. Just the 2 found previously. All I can conclude is that they didn't have grave markers when they were buried. Likely could not afford them. Is that possible?
3. Do you still want the 2 photos of the others that I found?
