Symbolism
Arms
The Canadian Heraldic Authority does not have confirmed symbolism for this emblem. The following comments are hypotheses only. A chevron and three birds are commonly found in the coats of arms of persons bearing the surname Rokeby, as well as in some Thomas coats of arms. The Cornish choughs are also known as “rooks,” thus making a canting reference to the surname. The maple leaf refers to Mr. Rokeby-Thomas’s Canadian nationality. The border is a Scottish method of differencing.
Crest
The Canadian Heraldic Authority does not have confirmed symbolism for this emblem. The following comments are hypotheses only. The sun appears in the crest of an English Nairne family and thus marks this aspect of Mr. Rokeby-Thomas’s ancestry. The trilliums refer to his home province of Ontario.
Motto
This Latin word means “I illuminate.” It connects to the sun in the Crest.
