reading through this old post i agree with jockscot most scots tend to stick to the fathers name ,
ive traced so far over 600 people on my family tree going back 700 years if i had to wear every tartan im related to i`d need to start saving up for over 120 kilts ,but each to there own if ya wanna wear a kilt then do so regardless or clans or kin... but i do hold certain family surnames closer to my heart mainly through association with that particular member of the family rather than status
