The Clesleepeel connection

Wont have much time to further evaluate the newly indicated SINTON connection for a fortnight or so, but a few quick checks on what I already have and what can be quickly added too, shows that there was a "son born to Jas SINTON of Clesleepeel" in the Southdean & Abbotrule, OPR on 4 Jun 1806. This is of an age to be the John marr. to Alison HALL who claims in the 1851 census that he was born at Southdean, and of Southdean when he married Alison in 1829. Other candidates are accounted for elsewhere, or at least most I know of are.
This father James is likely to be the James who married Barbary OLIVER in 1804, given that Barbara was of Clesleepeel when whe was buried in 1809, and this James' father is likely to be the James married to Janet OLIVER, given that he also was of Clesleepeel when he was buried 1802. (This is the family of one of my favourite death certs, Betsy WHITE nee SINTON, died "aged 96 of old age, 10 weeks duration" - Betsy was of Clesleepeel when she married John WHITE in 1801.)
Unfortunately, it is unlikely I'll ever prove any of this conclusively as they all died prior to civil registration and Abbotrule headstones aren't exactly plentiful if the photo on geograph is a typical view.
And as to how Peter and James relate?
There are two contemporary, or near contemporary James SINTONs in Southdean and Abbotrule who may or may not be one and the same person, remarrying, both are carriers: one having children 1755 thru 1760 (at least): Thomas, Margaret and James, wife as yet unknown; and the other marrying Janet OLIVER (?of Hobkirk) in 1762 and having children at Burnkinford 1763 and Strangeburnfoot 1765 thru 1769 and Burnkinfoothead 1772, dying Clesleepeel and buried 1802.
My Peter was a cattle dealer of Bairnkin when he was buried 1811. Assuming he was at least 20 when he and Janet DONALDSON married, he has to have been born around 1755 or earlier, so pre-dates the James and Janet (OLIVER) SINTON couple, but would fit in with the earlier James and ?? couple, most likely as the eldest son, given the first we know of is a 1755 Thomas.
Naming pattern of Peter and Janet's known children certainly indicates that his father is a James, mother possibly an Isabella.

In reviewing data, I have also combined two other Peters, both baker journeymen: one the reputed father of the Isabella SINTON (born c 1826, d. 1882) who married David HOPE, the other who married Marion KER in 1832.
