I didn't change my name, in part cuz I had already published a lot with my maiden name, and because the feminist in me didn't see the point and actually objected.

We gave our kids hyphenated last names. The only problem its caused, which is minor, is that its a PITA to make airline reservations since we have 3 different last names for one family traveling together, but now that is done online so its easier. Also, some computer systems still have trouble to handle hyphenated last names. And I have no CLUE what my kids will do when they marry but that is their problem.

My husband is portuguese, and I like their custom which is what Mimi described, the women's maiden last name becames her middle name when she marries, and then she takes her husband's last name. So, its not hyphenated but she can use it as much as she likes or needs to. In fact, she accumulates these middle names as the generations marry, kind of like a lineage.
