> I read Daisy's post as people NOT marrying but simply adding their partners name to their own without legal record
Yes and no :) :) This practise can cause many future problems :) If it isn't the 'norm' people in the future won't know what name to look for in records - do people put the man's name first or the woman's ?? What name do the children have ? If they have the double-barrelled name, what will they do when they marry ? Who is using the name - everyone or just the woman ?? Family research was comparitively easy until recently because the conventions were set (more or less) for naming. Now - in some cases - there is no convention, just whatever people choose. When I was at school, there was a girl on the Honours Board who had a triple-barrelled name - the first and third name being the same ........... :) :)
St Domingo - if I look your marriage up in the records, it will show Mr A marrying Mrs B - it will not show (unless you both gave your new double-barrelled name when you married as your unmarried name) that you are now Mr & Mrs A-B, so researchers, for example, won't look for children with the new name.
It's probably not important to you - only to people, like me, that do family history research :) :)
