There have been rules for this for centuries in the UK. Pre-hyphenated names wre combined on marriage as <woman's_family_name>-<man's_family_name> On two people with such names marrying the final married name is <first_part_of_woman's_name>-seond_part_of_man's_name> Archaic, I know, but there it is. I guess it all breaks down if you don't follow the rules in the first place, and since the rules are just some of the arcana of the british class system, who knows and who cares about them?
