I can add just a tiny bit more information to this family plot.
A Plot Book existed for this burial ground and listed burials there begining at 1901 and ending around 1954 (with a few cremation caskets up to about 1963).
This book was in the care of Motherwell District Council (taken over by North Lanarkshire Council) and free access was given to anyone who asked to view it. Unfortunately, it was stolen and never returned. Fortunately, a good friend of mine, who has ancestors buried in the Old Manse, transcribed this book and gave me a copy, so all is not lost! The book uses the plot numbers allocated on the plan drawn up by Alexander Bryden Assistant Inspector of Poor in 1893.
So, I am using Bryden's map, a copy of which I have in front of me, to give what information there is on 20th century burials within this Smellie plot. He has 4 graves marked as numbers 44, 45, 71 & 72. This makes up a large oblong-shaped plot with one-third of the lower left side missing!
A grave in those days held generations of people, not just 3 or 4 like the modern ones of today.
All dates are of burial.
