Hi Bonnyjean,
I found 6 burials in the Cambusnethan burial records relating to this family.
2 children are buried in public ground (paupers graves) the others are all in the one plot, in section D of the cemetery, number 273. So, you contact North Lanarkshire Council Cemeteries Office, quote Cambusnethan - D273 and they should be able to tell you the names, ages and dates of internment of everyone buried there, also who the owner of the lair is. (the owner may very well be one of the deceased). I don't have all the records, so couldn't find Bridget, I think she may be in a pauper's grave but, the office may know more.
Here's what I found -
JAMES DONNELLY. Newmains, aged 20 months.
Parents - James Donnelly and Bridget Farrell.
Interred in public ground 29 June 1872.
HELEN DONNELLY. Newmains, aged 3 months.
Parents - James Donnelly and Bridget Farrell.
Interred in public ground 25 December 1872.
JOHN DONNELLY. Steel worker, Wishaw, aged 24 years, single.
Parents - James Donnelly and Bridget Farrell.
Interred section D.273. 11 July 1893.
THOMAS DONNELLY. Coal miner, aged 25 years, single.
Parents - James Donnelly and Bridget Farrell.
Interred section D.273. 24 October 1899.
CHARLES FOY. Wishaw, aged 9 months.
Parents - Patrick Foy and Helen Donnelly.
Interred section D.273. 21 August 1907.
BERNARD DONNELLY. Coal miner, Shieldmuir, aged 35 years, married.

Hope this helps,
