A Google search netted me "Down under with the Prince".  Scrolling down the page to:

66 DOWN UNDER WITH THE PRINCE

It mentions the shot-torn colours carried by the third British Foot Guards at the battle of Alexandria as long ago as 1801 and that these colours had been handed down through the generations by NZ descendants of Colonel Samuel Dalrymple who was in command of the regiment at that time.  The account went on to say that the colours, which apparently were the only ones belonging a Guards regiment, preserved elsewhere other than the British Islands.  They were presented to HRH the Prince of Wales, by Mrs J H Hankins, nee Dalrymple, who is, in fact, Agnes Sophia Wemyss Dalrymple.  This took place in Palmerston North, NZ.

I have found a reference to what Glamis might be talking about..

There is a 600 year old Gothic cathedral, built over the tomb of St Mungo, in Glasgow, Glasgow Cathedral, also called the High Kirk of Glasgow or St Kentigern's or St Mungo's Cathederal, and amongst its treasures are the faded and bullet-holed colours of the Scottish Regiment of Foot Guards from the Egypt Campaign of 1801.  Apparently there is a label that says they found their way thanks to Mrs Hankins of Palmerston North.

If you go to Google Books and type in:

Christian Dalrymple Hugh Stuart it will turn up lots of bits of information on the 2 of them as well as useful details on the family.

There are some very excellent revelations in that will. 

George may eventually have received a substantial legacy; it was 'expectant' on the death of Hugh Stuart.

Unless I missed it somewhere, I suspect we need to find the will for Hugh Stuart to find out.

Although, in the interim, Little Nell is right.  A paper version would indeed help.
