Marc,
I have my Gran's birth cert 8/1/1895 which states her mother was Margaret Grey (M S Mcintyre) born 15/2/1878 holy Isle, Lamlash.
I understand M S Mcintyre was one of a large family of 8 girls and 3 boys who lived in the white house on the island.
I too have stayed there around the early 1950's.
One of the other island sisters also married a Paterson who had a son John Paterson who I think in turn married his Cousin being my gran!
GW I will visit Grace next week
John
