Icelanders manage OK without surnames. They use patronymic (or sometimes matronymic) instead.
I was told that that was irrelevant since due to some odd incidents of breeding patterns they tried to make the phone book a couple decades back and discoverd that of the millions of people listed, that predominantly the bulk of them only had four different (apocryphal story, let it go.) surnames so the powers that be, just said "fuck it" to save money on ink.
I mean historically surnames are only there to stop inbreeding, pronounce a profession or help the tax collector keep track of who is running away from his open purse.God knows where the pride comes from.

If Chakotay used this method and called his son Clyde, his son would be known as Clyde Chakotayson. If his daighter was Kathryn, she would be known as Kathryn Chakotaydaughter. Or the children might use their mother's first name as a matronymic.
Women are known all their lives by the name their were given at birth and never take the husbands' names.
Of course, in all likelihood, Chakotay would give his some an Indian name.
Neelix and Tuvok don't have last names.
Tuvok is married. But then Vulcans get engaged shortly after birth. There might some appendage, affectation to the name then abouts, so that never "child" forgets what their family expects of them?
Or perhaps Chakotay's "full name" is Chakotay Son Of Kolpak. In this case his son's name would be, for instance, Clyde Son Of Chakotay.
HILARIOUS!

Seven was not too fond of her given name, so perhaps her name remained as Seven Of Nine when she would have married Chakotay.
I usually roll my eyes 10 generations atfer the fact (Although I've only ever seen this said in fiction on TV and Movies, although I 'm just young enough to have no recollection of seeing Roots, but Chappel did a hilarious pistake on the Kunta Kinta whipping scene.) that the Dutch snared their ancestors up in a net and ferried them off to America, that some one says "That is my slave name!" However in sevens case, that's pretty damn acurate.
Why should a woman take the last name of his husband? I know it's a surprise to some, but among all western nations, it's only in the US that it's still customary.
Uh, there are MANY countries where this is customary.
Personally I don't care either way, but you're just flat out wrong here.
In the world, you are right. But in the western hemisphere, only Anglophone nations still do that, and in the UK it's a declining trend (if I remember correctly). Honestly, I don't know about Australia and New Zealand.
I'm looking about out my window and I can smell the after woft of plenty of pretentious wankers who need to prove that they are not cattle, but over all marriage is just a lark and name changing is just part of the game, though I have a Dutch friend who was just overjoyed to take on an English sounding name so that the natives here would stop butchering her own mother tongue. However half a world away and 5 years later, she remarried an immigrant Ducth fellow and shes back to square one with a new unpronounceable name all the stupid Kiwi's can't quite get their tongue around.
I got Fiddler on the roof hammering through my memories right now.
"Tradition! tradition!"
Yeah, but tradition of
who? Neither Seven nor Chakotay apparently belong to culture where it's customary for the wife to assume the surname of the husband, or vice versa. You are applying a tradition to people that do not share it.
I defy you to prove to me that Seven of nine or Chuckles are not early 20th century Hasidic Jews?
Neelix and Tuvok don't have last names.
Vulcan family names are also confusing. Apparently the use the patronymic (Spock, son of Sarek), and in very formal occasion the double patronymic (Sarek, child of Skon, child of Solkar). Many novels assume that they have clan or family names. It could be the "almost unpronunciable for a human" name that Spock never told to Leila Kalomi, or the one that Spock's mother had difficulties to learn in Journey to Babel.
About Talaxian names, I do not want to know.
Neelix is probably on the run for charges of pedophilia, gotta keep his ears low, although since they call him Neelix and Mr. Neelix depending on the occasion, maybe his name is Neelix Neelix? The Hedgehog so hedgehoggy they named him twice?
