A wee bit Scottish... but I didn't want two clan badges
So mum's side on the right arm (the star is a copy of the actual silver badge from Scotland - inaccuracies and all). CAVE ADSUM - beware I am here (or beware I am present) ... I'm right handed if you get my drift.
And the crest is my dad's side sept of the the clan (on left arm).
AD FOEDERA CRESCO = I gain through treaty (makes sense for weak arm)
