It says Consilio non impetu.I can see it well in the book.
I am not sure about the engraving in the stone.It looks as if the person who did it was not really a professional.I can see that there was an attempt to carve the same flower look as is found on the crest on page 431.The proper term for the one on the grave marked would be the crowned heart of Douglas.That would be the heart of Bruce that James Douglas took on the Crusade in an attempt to carry it to the Holy Land for Bruce.
The way I understand it is that they were showing the descent of Captain James Agnew from Robert the Bruce.
The Agnews of Lochnaw do descend from Robert the Bruce through Mary Kennedy and Andrew, the first sheriff if that marriage did occur as Sir Andrew writer of Hereditary Sheriffs states.
The descent from Robert the Bruce occured through the Children of Quentin Agnew, of Lochnaw, 3rd Hereditary Sheriff and Mariota Vaux.
The descent occured through the choldren of Sir Patrick Agnew, of Lochnaw 1st Bt, 8th Sheriff and Margaret Kennedy.
Margaret Kennedy had the blood of Robert the Bruce from the Kennedy line and The Campbell line as well.The Great Grandmother, Lady Isabel Campbell, descended from Robert II Stewart, King of Scotland through Robert Stewart, 1st Duke of Albany and the marriage of his daughter, Lady Marjorie Stewart, to Sir Duncan Campbell, 1st Lord Campbell OF LOCHAW.
I believe that the Grave marked is showing the descent of Captain James from Robert the Bruce.It could not mean anything else.
In Burke's "Colonial Gentry" Burke wrote that the Sir Andrew Agnew approved a differenced version of the Arms of Lochnawfor the family of Sir James Wilson Agnew.The use of this version of the Hereditary blazon was assigned by the daughter of Sir James Wilson Agnew to the line of Captain James Agnew (1711-1770) which has been again been differenced by the thirteen stars for the "Thirteen Original States" but theser arms were only bestowed by courtesy of the possessor as the gracious acknowledgement of relationship.The Hereditary bearings, as carven on the stone of James Agnew are the proper armorials for lineal descendants of Captain James Agnew (1711-1770).
See page 441 for more information on this. I believe that the engraver should have made the stars or flowers with 5 leaves.I do not understand what they are to be.
I do believe that I understand that he intended to show descent from Agnews of Lochnaw and Robert I Bruce.You can see the pen and ink version on page 431.I like the one on the page between 430 and 431 with the thirteen stars.
If I understand this the proper arms for James's descendants is the one with the Crowned Heart of Douglas.Actually the Crowned heart of Douglas on the Douglas coat of Arms is a red heart with a crown on top of it.What we have here is a Crown over the coat of arms which has a heart in the coat of arms.I am sure that this must be the Heart of Bruce with a crown in place of the Hereditary Crest.
The Douglas call it the Crowned Heart of Bruce.There was a lot going through the mind of Captain James Agnew with the design of this.It is clearly Lochnaw but with his own version of a Coat of Arms.
I do not understand a lot about Coats of Arms.I say that this speaks a lot.
