Rev. Robert Monteath

[WilliamD]

James Monteath, son of Walter Monteath of Kepp & Jean Douglas ... his elder brother Major Archibald Monteath who... took the name Douglas.

They share the Mausoleum in the Glasgow Necropolis.
These two had another brother (there were eight in all), Thomas Monteath, who, if I have this right, married 'the surviving daughter of Sir William Scott of Ancrum' and inherited his estates. This would appear to be Constance Scott, 9th Baroness of Ancrum as the baronetcy technically ends with this William. Thomas was buried in the Mausoleum at Ancrum in 1856.
My problem is that there appears to be another Thomas Monteath Douglas, born before 1810, who whose daughter, Amelia, married William Scott, 7th Bt of Ancrum. Who was he?

Adding a reply from mpwarner -

I wish to respond to Skoosh, Buckhind, and William D who wrote in 2013 re Monteaths. They may consult book "Archibald Monteath" by M.Warner-Lewis, chaps 4 & 5.
