John,
Do you have access to FindMyPast or any newspaper site?
There are a few articles in various newspapers but there is one interesting article in The Stirling Observer relating to this family.
It is dated 14 Nov 1867
It is about a family reunion of 104 people, representing 9, families, all descended from " A Novel Character" named JOHN Currie of Eaglesham.
The article gives no indication of when this man died, or if the descendents were children, grandchildren etc, but at a guess, it probably relates the man who died in 1854
It was Robert Currie of Eaglesham who presided and was supported by 4 younger brothers.
It suggests that at 1867, the late John Currie had 5 surviving sons
( I presume this is the case, although it's not absolutely clear)
Due to T&Cs, I cannot post the article on here but, I can provide you with it if you contact me by PM with an email address
The 1872 death announcement for Elizabeth Fulton, widow of Robert Currie appears in The Glasgow Herald dated 20 May 1872 and is found on page 5
Note that Australian and US papers were asked to copy.

1854 death of John Currie also appears in Glasgow Herald dated 16 Oct.
Also on page 5 and can be found using above link.( alter the year search)
Also, if his eldest son was named Robert as per the 1867 article, it suggests that Robert would be the name of John's own father which fits with DonMs post at 17.12
