Hello Glynn,
If it helps at all - in the 1828 Black Book (List of Tenants on the Estate of Islay), I see a listing for "Neil McDearmid's heirs" in Bowmore.  No specific address back then.
I typed up this list  back in 2000 (which is what John referred to in aprevious email), but I also still have a photocopy of the original.
