As part of a local kirkyard project in the north of Scotland we have uncovered a fine re-used 'Calvary Cross' tombstone. We believe stones of this kind date to the mid to late Middle Ages. The original stone shows a sword running the full length of an ornate wheel pattern or cross with a central boss. Later initials have been cut into it, partly obscuring the wheel pattern: AS & KS in one place and IS & MF (probably earlier) in another. There are other Sinclair burials in the kirkyards concerned. How far back does the Sinclair family tree go? Does anyone recognise these initials as possibly belonging to any particular Sinclairs?
