Friar Mark Hamilton

The text includes an old family tradition that has been described as a "fabulous story".[6] The History states that Robert the Bruce gave the lands of Kinneil to Gilbert Hamilton, "for his trew service and greit manheid," and especially for having slain "for King Robertis pleasour the great lieutennand of Yngland upon Kynnale Muir. " Gilbert Hamilton had been with Robert Bruce at the battle of Bannockburn, and was one of the seven knights of the royal bodyguard. A large stone was said to mark the place where fight took place.[7]

For Sir Gilbert's exploit on Kinneil Muir vanquishing "Odomar Vallance" the Welsh-born Lieutenant of Edward II of England, Friar Mark tells us, "King Robert gaif till him his armis till weir in Scotland thre sink fuilzies in ane bludy field," or modernised: King Robert gave to him forever to wear in heraldry in Scotland three cinquefoils in a blood red field.[8]

"Gilbert Hamilton" represents the older brother of a known historical figure, Walter fitz Gilbert of Cadzow. "Cadzow" is an old name for Hamilton, South Lanarkshire. Sir Walter's arms appear on the Bute Mazer, a famous cup held by the National Museums of Scotland.

Friar Mark says the younger brother Walter fitz Gilbert was red haired and ruddy in complexion, traits inherited from his Scottish mother. He was schooled by the monks at Dunfermline Abbey. Their father was "Philip , Earl of Southampton", in England.[9] The actual relationships of these early members of the Hamilton family are unclear.[10]

Friar Mark wrote that Isabella of Mar was; "ane of the warldliest ladiest that was in that tyme scho was King Robertis sister douchtir and till erle Thomas Randell his full sister quhais name was callit Isobell ane madin of twenty yeris of aige of vertew & of greit honour maist excelling undir the quene for that tyme". In modern terms, Isabella was "one of the most chivalric women of that age, the niece of King Robert and sister of Thomas Randolph, she was a maiden aged 20 of virtue and great honour exceeded only by the Queen of Scots."[11]

The final section of the manuscript text is the "Oratio Gilberti Hammiltoune in funera Roberti Brus Regis" - the prayer Gilbert Hamilton said at the funeral of Robert the Bruce at Dunfermline Abbey in 1329, which includes this oath;

"quhill that his life in erd may lest with hart & mynd, constant the rycht of Scotland ay for to defend with manheid invinciable, his body evir for to spend for Scotlandis common weill the charge of weris, say for to failye withe all kind of jeappedry."

As long as his life on Earth lasts in heart & mind, so constant shall be the Scottish people's right ever to defend Scotland's commonwealth with invincible courage, as in his body, against the expense of wars, and not fail in the face of kinds of hazards.[12]

By these lines, Friar Mark may have meant that the Hamiltons were bound by memory of King Robert to sue for peace on behalf of the Scottish people, the common weil or "common wealth". It is not known if this prayer was in reality said at the king's funeral.
