On changing one's name

[Ancienne Alliance]

It's not actually a Scottish tradition to hyphenate surnames. I stand to be corrected (please) but I think that hyphenating surnames creates a new name. So Mr Sporran and Miss Purse marry and name themselves Mr and Mrs Sporran-Purse, thereby creating an entirely new and different surname, Sporran-Purse. In Scotland; I've no knowledge of the laws in the US.

Not wanting to high-jack this thread I would like to add that for ceremonial purposes like Clan certificates or brevets, etc. , I sometime use the full name version my ancestors bore. That makes it :
Robert Amyot de Villeneuve-Lincourt



Best,

Robert
