Thanks Lodger,
That one small piece of solid evidence has already solved one of my mysteries! I had been searching for a marriage for Agnes McConnell (born 01 Sept 1858) for ages as I hadn't found a death record and so already that's one I can cross off my list...
William and Rachel had another Robert born 16 Sept 1856 but he must have died too as a baby/young child as the second Robert was born on 03 Mar 1861.
The other children from the marriage were:
Hugh McConnell b 1849 (married to Marion ?)
William McConnell b 1851 (married twice second time to Marion Stobo)
Christina McConnell b 1853 (married Thomas Saddler)
Isabella McConnell b 1855 (married ? Maley)
Robert McConnell b 1856 - died before 1861
Agnes McConnell b 1858 - died 1862 (THANKS!)
Robert McConnell b 1861 (married Agnes Topping Waddell)
Mary McConnell b 1863

?
John McConnell b 1865

?
James McConnell b 1867 (married Elenor Campbell?)
David McConnell b 1869

?
The McConnells were a mining family and they did move around quite a bit so it's difficult to keep track of individual family members. I haven't been able to definitely trace any of the family members deaths to mining accidents either.
As for all the Topping information you have kindly provided, I will have another look at my information - I have some deaths of Toppings at Shotts because of the mortcloth records so I'm sure to find some links there.
Thank you so much for your prompt reply. I live in Australia and as I haven't yet managed to win the Lotto unfortunately I can't see myself getting over to Scotland any time soon...
Warm Regards,
Jen
