Ewwwwww I would have no respect for a man that takes a womans name. That is just wrong.
So, if your family name was 'Sczakenquentina' and your wife's name was Jones; you'd want to stick with 'Sczakenquentina'? And yes, there are far worse last names than that... I think we both know of some real names that are unprintable in this forum.
If you have a 'doozie' and you decide to stick with it, do you think you are doing your children any favors?
This is actually quite common in Latin American countries.
