GeneralSP: Seems to be the true ancestor of the Hamiltons of Raploch...
Notes for Walter Hamilton
Scots Peerage writes, Vol IV, p. 347, of his son James' acquisition of Raploch, starting with this Walter:
"Walter of whom little is known. He is named in a charter deted 20 May 1441, by Sir James Hamilton of Cadzow, afterwards Lord Hamilton, granting to his cousin James Hamilton, son of the late Walter Hamilton, the lands of Raploch, co Lanark [3]. This Walter therefore seems to be the the true ancestor of the Hamiltons of Raploch and others. The Thomas referred to in this connection in the "House of Hamilton", and described as of Darngaber, is not found so styled, and he appears to have been a servant and not a son of the family [4].
