About the St Clair surname

From Stirnet's "Sinclair09" page (membership required to view without interruption): "BP1934 reports that 'Two important families bearing the name of Sinclair (or St. Clair) co-existed in the 12th century, distinguished as of Rosslyn <membership required to view without interruption>, in Midlothian, and of Herdmanstoun, in East Lothian. Though no relationship can be traced between them, the earlier bearers of the title of Lord Sinclair belonged to the former, while the later belonged to the last named family.'"
