Hi Liam,
I visited St. Mary's cemetery, opposite St. Mary's Church Edenderry, today, took some photo's.
Just to confirm headstone inscription in St. Mary's, Thomas O'Kennedy died 29th. ? 1957, His wife Pauline O'Kennedy who died 18th. Dec. 1960.
There is no mention of his first wife Winifred or his daughter Emer on the headstone but Emer is buried in the grave. I know this because she is recorded in the book Carved in Stone, compilled by Therese Abbott who was a neighbour of Emer when she lived in Windsor Lodge. I also knew Emer when I was growing up, she was a lovely lady.
The grave and headstone in St. Mary's is in good condition but needs cleaning.
Winifred is probable buried in Drumcooley, about one mile outside Edenderry, having died in 1931 she is not buried with Thomas, Pauline, or Emer, because St. Mary's was not opened until 1955. There is no headstone to Winifred in Drumcooley, or any record of her buriel in Carved in Stone. Drumcooley is a very old Cemetery and some headstones have fallen, broken, buried, and have been lost including my own Great-Grand Parents. Winifred could be buried with her parents, I would need to know her maiden name to search further.
If you let me know your phone no I can send photo's on Whats App.
My research shows no family connection but if you go back far enough there probable is.
Regards,
Rory
