I have a old friend from high school whose last name was Titus, he married a woman whose last name was Dahl.

They have since been known as Mr. and Mrs. Titusdahl, no hyphens.

I guess that just means you can do pretty much whatever you want as long as you legally register the name.

Tank (who thinks it's fine for people to keep their own names after marriage but finds strange amalgams rather pointless)
