Newbie:- A lot of 'internet genealogy' readily produces all sorts of interesting ancestry although a lot of 'on line' family trees have little or no supporting evidence, sources or references and some have glaring errors in them.

Mainly because of painstaking work by an established family history society I am as certain as I think one can be of some ancient ancestry but there are several lines e.g William 'the Lion' and his forebears, Juliana Dunbar and her forebears etc. I assume these pre-date any named Tartans so any advice please on which Tartan(s) would be fair to choose? Are there general Tartans that would suit? Thanks for any thoughts or suggestions.
