Lady Tremaine could have anywhere from one to four surnames, or possibly even more. As we discussed on another thread, it's reasonable that not every family would have surnames -- in medieval times, they were only taken by people who had reason to carry on their legacy. So she may or may not have a birth surname.

If she's Rapunzel and we're going more Tangled where she legitimately believes that the witch is her mother, she could have her kidnapper's surname. ("Rapunzel Gothel" or something.)

Then she probably married someone, resulting in the birth of Drizella. Drizella likely has a sister, but they could be half-sisters. There could also be more than two wicked stepsisters. So at least one, probably no more than three, husbands could be fit in here; if they had surnames, which is likely since Tremaine wants to climb the social ladder, she likely took them. But she may have changed her name back after their death/divorce/whatever happened.

And lastly, she marries Cinderella's father. Once again, she likely took his surname but could have changed it back. So Cinderella might be Cinderella Tremaine, or one of her past husbands may have been Lord Tremaine, or her kidnapper may have been a Tremaine, or her birth family could have been the Tremaines.

Long story short, she is likely Rapunzel Tremaine now - if she even kept the name Rapunzel post-kidnapping - but wasn't necessarily born that way.
