Can you make out the initials on the monogram here?  Among some very fine old houses in Inveresk is the Manor House which has an imposing pediment with the date 1748 and a monogram.  The house was built for Archibald Shiells who was a very prosperous merchant and owner of many properties which he let out.   It is not easy to distinguish his initials although I can see an A.    One of the later residents was the geographer and cartographer, John Bartholomew whose maps and atlases became very popular.
