Basil Blair Basil Blair now has a Find-a-Grave memorial page. I will photograph the grave tomorrow, but I doubt that there is a stone. At any rate--it's an interesting story. I copied the NY Times story of his murder onto the memorial page. I do not know how he is related to the Stevensons, several of whom rest in lot 1233.
