It really is time I posted a Sinton update!

What would be great is to refine the below current yDNA tree of Sinton-kind from the Scottish Borders .

The branch of the "Jedburgh" line down from William Sinton married to Isabella Scott looks the easiest to achieve as even the incomplete tree of William's yDNA descendants on WikiTree shows several lines close to present-ish day. The current branch R-BY113535 is from the BigY results for a descendant of son Andrew. 

To keep an eye on any progress, see the current TimeTree version of the main branch of the Scottish Borders Sintons and how they connect to the overall tree of mankind.

Here's a screenshot for historical reference, and in hope of future refinements thanks to new testers:
