Logical consequences of nested naming

I made an interesting discovery today. Suppose your name is hyphenated, Newgard-Larson for example (my high school english teacher). Further suppose that you have sons and they grow up and become engaged. Since your parents considered it not preferable to suppress the maiden name, perhaps you or your fiance have a similar predilection. Suddenly you are presented with a quandary; does your fiance follow suit and add her maiden name to the previous portmanteau and create a double hyphenated moniker? Obviously this method of preserving the maiden name is not sustainable. Naturally it is impossible to preserve the maiden name through multiple generations while simultaneously preserving the given name through the same. Something has got to give.

Furthermore, suppose the finace has a hyphenated name of her own. Now we not only have a name with three hyphens, it is not obvious if name number two of four was the husbands grandmothers or mothers maiden name, since the wife could have added one or two of her own and three names must be possible to bring into a marriage else the original maiden name would be lost. Perhaps parentheses would be preferable to hyphens.

Suppose we abandon the pretense of preserving the maiden name beyond one generation, then the hyphenated name decision serves to preserve the maiden name for its former owner. Do the children have the same last name as the parents? If not then all children must have their given name changed at birth, if so they must have their name changed at marriage to prevent the name cascade. Of course the new fiance could replace her maiden name with the hyphenated name, but does it really make sense to give precedence to her mother-in-law's name over her own? So, both husband and wife change their name to delete the former maiden name and replace it with the new. This system is sustainable, albeit at the expense of two name changes instead of one (which happens anyway with hyphenated names) and at the expense of preserving the previous generation's maiden name.
