On FindMyPast Newspaper search there is a mention in the Caledonian Mercury of 15 Nov 1744 of some sort of legal action "depending before the Lords of Session, at the instance of Leonard Small in Tarvie, against Spalding of Assintully and his Creditors". Assintully is modern day Ashintully.
Interesting. Looks like it's some sort of financial debt owed perhaps?
A Leonard Small and Ann(e) Robertson had 2 children in Moulin around this time. I will assume it's the same Leonard Small here.
Details of the children they had;
Christian Small b. 28/10/1728 Kirkmichael
Twins!Anna Small b. 28/10/1728 Kirkmichael
Alexander Small b. 09/03/1730 Kirkmichael
Patrick Small b. 28/07/1737 Moulin
Leonard Small b. 02/07/1744 Moulin
Leonard Small and an Anna Robertson married in Moulin on 21/03/1727.
Anna must've come from Moulin also as only one entry came up for this marriage for the entirety of Scotland.
I've noticed a very hefty amount of different Small men marrying a Robertson lady in Moulin and Kirkmichael. Would this be some sort of agreement between the families perhaps?
Also I notice the latter two children born above were born in Moulin in comparison to Kirkmichael, so they either moved or the boundaries had changed. Having looked at older maps the areas in which my Smalls lived were extremely close to parish borders. So this could be a redefining of those perhaps between 1730 and 1737?
Interestingly Leonard and Ann(e)(a) didn't have any children after 1744 and this article was posted in November 1744. Potentially some financial reason there with that decision
