Ard, here's what I found, it makes sad reading.
HENRY McPHAIL, Wishaw, aged 8 years.
Parents - Henry McPhail & Agnes Lafferty.
Interred in common ground, 22nd November 1862.
WILLIAM McPHAIL, Wishaw, aged 3 years.
Parents - Henry McPhail & Agnes Lafferty.
Interred in common ground, 3rd December 1862.
AGNES McPHAIL, housewife, Wishaw, aged 32 years, married.
Parents - William Lafferty & Margaret Blair.
Interred in common ground, 17th December 1862.
SARAH McPHAIL, Wishaw, aged 6 months.
Parents - George McPhail & Isabella Wyper.
Interred in common ground, 3rd October 1876.
HENRY McPHAIL, labourer, Wishaw, aged 57 years, widower.
Parents - Archibald McPhail & Margaret Crichton.
Interred in common ground, 30th March 1878.
MARION McPHAIL, Wishaw, aged 2 years.
Parents - George McPhail & Isabella Wyper.
Interred in E56, 25th November 1893.
ARCHIBALD McPHAIL, tailor, Wishaw, aged 33 years, married.
Parents - Henry McPhail & Nancy Lafferty.
Interred in E55, 7th August 1896.
ISABELLA W. McPHAIL, Wishaw, aged 1 year.
Parents - Matthew McPhail & Marion Ballantyne.
Interred in E56, 28th April 1900.
E55 & 56 must be a double plot, so it's all the one family.
It may be some consolation to know that little Henry, William and their mother Agnes who died within the space of 25 days of each other, are all interred in the same common grave, number 138.
I will go to the cemetery and check if there is a stone at E55 & 56.
