Hi Dawn,
I thought I'd cracked the case with that burial! Never mind, here's what else I found.
I should say that the "new" cemetery was opened about 1861 and is adjacent to the old churchyard at Cambusnethan village. The "Clyde" burial ground pre-dates the old churchyard and is the original parish graveyard, next to the river Clyde at Kirkhill. The original parish church was there until it was abandoned around 1648. The successor to this church, on much higher ground at Cambusnethan village, was itself abandoned about 1820 and sits in the "old churchyard".
So, although the burial ground at Kirkhill was used very infrequently as the centuries went on, the last internment there did not take place until the 1950s. But, it was only used by real old Wishaw/Cambusnethan families, also by farmers and orchard keepers on the Wishaw Estate. (Trotterbank would have been leased from Lord Belhaven of Wishaw House).
There were only 2 recorded burials at Clyde/Kirkhill in 1929.
From the Cambusnethan cemetery Day Book -
(all dates are of internment)
JANE S. NAPIER. Trotterbank Orchard, aged 11 weeks.
Parents - James S. Napier & Margaret S. Merrilees.
Interred in the new cemetery, plot D311. 15th April 1890.
AGNES MERRILEES, housewife, Trotterbank. Aged 65 years, married.
Parents - Alexander Smyth & Helen Hamilton.
Interred in the new cemetery, plot C316. 3rd August 1893.
WILLIAM MERRILEES, orchard keeper, Trotterbank, aged 78 years, widower.
Parents - Robert Merrilees & Agnes Roger.
Interred in C316. 10th April 1900.
Next, this is the Alex I've given you already but to keep it all together, he is interred in the old churchyard, the records do not exist for internments there prior to about 1875. For this plot however, there is a headstone with the following inscription (note the spelling)
"Alexander Mirrilees died 11th February 1879 aged 51 years. His wife Rebecca Russell died 6th January 1912 aged 85 years. There daughter Margaret Reid died 28th February 1871 aged 5 years".
From the plot book for the old churchyard, the owners of the above plot were Alexander Merrilees & Rebecca Russell.
All of the following were interred at the Clyde burial ground -
ROBERT MERRILEES. Farmer, Erskine Bank, aged 82 years, married.
Parents - Robert Merrilees & Margaret Fleming.
4th September 1861.
ROBERT MERRILEES. Carter, Gowkthrapple, aged 49 years, married.
Father - Robert Merrilees. No mother's name stated.
16th October 1861.
AGNES MERRILEES. Housewife, Erskinebank, aged 78 years, widow.
Parents - William Roger & Agnes Kilpatrick.
15th June 1865.
ANN MIRRILEES. Gowkthrapple, aged 49 years, widow.
Parents - John Scott & Jane Cleland.
24th November 1866.
AGNES MERRILEES. Housekeeper, Wishaw, aged 64 years, single.
Parents - Robert Merrilees & Agnes Roger.
18th December 1879.
You don't mention a David in the family but this next one may be a son of Robert Merrilees & Ann Scott, especially as he is at the Clyde burial ground too.
DAVID MERRILEES. Wagon driver, Wishaw, aged 45 years, married.
Parents - Robert Merrilees and Ann - - - - - .
10th April 1878.
(I think David's wife may have been Agnes Prentice?)
finally, one of the 2 entries in the Clyde register for 1929 -
MARION MERRILEES, aged 68 years.
10th July 1929.
I'm pretty sure Trotterbank is still there, at the foot of the Brownlee braes near the junction of Horsely Brae between Overtown and Garrion Bridge. Erskine Bank is still there too, half-way up the Horsely Brae on the left.
I'll check the Cambusnethan registers again for any of the Merrilees clan I may have missed.
Also, I found this entry and wondered if perhaps the informant didn't know the correct names of her parents -
JANET STEEL. Wishaw, aged 72 years, widow.
Parents - John Merrilees and Janet Roger.
Interred in the old churchyard, 27th October 1913.
