The Banner of the Lodge like its Founders Jewel, bears the arms and name of the ancient family of Muschamp.

That family first comes into history A.D. 100-1135, when King Henry I bestowed an extensive barony on Robert de Muschamp.

This baron included Belford, Wooler and all the country in Glendale and Norhamshire and Islandshire which had not been assigned to the barony of Walk or the Bishopric of Durham.

Barmoor (then spelt Beyirmoor), Ford and Etal were manors in the Muschamp barony, - the two latter being held by Odinel de Ford and Robert Manners respectively for half a Knights fee each. To this day the owner of Ford pays the owner of Barmoor £5 per annum as tithe in lieu of 12 men-at-arms from Gatherick. A Muschamp built the castle at Wooler and a hold to contain 40 horsemen at Barmoor.

When King Edward III, after the battle of Halidon Hill A.D. 1333 left England for the war in France, he took every available fighting man with him and left the border very much unguarded.

Accordingly he gave licences very freely to landowners in Northumberland to crenellate or fortify their dwellings. Amongst them Heron of Ford got licence A.D. 1338: and A.D. 1341 licences were granted to Grey of Walk to crenellate Chillingham, Muschamp to crenellate Barmoor, (he added a round tower to the hold) and Manners to crenelate Etal.

Robert Manners was an ancestor of the present Dukes of Rutland, and his coat of arms on the gate of Etal Castle are identical with the old arms of the Muschamp family (i.e. or, two bars azure, a chief gules)

Later on in accordance with the fashion of the day, the Muschamps assumed a coat of arms pursuing on their own name, azure, 3 butterfiles argent.

After the visitation of Northumberland by Norroy King at Arms A.D. 1615 the Mushchamps pedigree was registered in the College of Arms and three house flies of gnats replaced the butterflies, “musca” being the Latin name for a fly. Yet the older coat carried butterflies, and they are emblazoned on the Banner of the lodge. The Muschamps evidently liked to be a little different from their neighbours , - butterflies instead of ordinary flies on their shield, and instead of a seal they attached to deeds and parchments a knife, with which they carved their venison from the Cheviot and their salmon from the Tweed. The mantling of roses which surrounds the coat of arms on the banner is copied from similar mantling around the arms of the family of Lee in Shropshire – ancestors of the first master.

At the time Heart of Glendale Lodge was founded it was impossible to obtain silk for armorial banners, even for the Knights Grand Cross of the Bath whose banners hang in Westminster Abbey. By the goodwill of a worthy brother the silk was produced and the Banner emblazoned at Shrewsbury.

The Sitwell Family have long held lands in Shropshire as well as in Northumberland. When William Sitwell was appointed first Master of Heart of Glendale he had just vacated the chair of S Alkmund`s Lodge at Whitchurch, Salop.
