GRAHAM
As described in historical dictionaries
Patronymica Britannica (1860)
GRAHAM. The name h;>s always been written interchangeably with Gramme — the Scottish oi'thography. The earliest traceable ancestor, (for we reject of course the fifth-century hero Greme — See Gramie,) is AVilliam de GRAHA,\r, wlio settled in Scotland early in the XII. century. The surname therefore is clearly local, and from its termination undoubtedly English. The onlv place in S. Britain of the name which we find is Graham, near Kesteveu in Lincolnshire.
