That applies ONLY to the so-called royal house, not the defunct Romanian throne, though. I think the family name remains the same as well.
Actually, if you read the Fundamental Rules that King Michael signed, you will see that a specific Line of Succession to the THRONE of Romania is laid out (to the complete exclusion of the the German Hohenzollerns, who would have ended up "succeeding" to the throne under the old laws):
1.HRH Crown Princess Margarita of Romania, Custodian of the Crown of Romania
2.HRH The Princess Helena of Romania
3.Nicholas de Roumanie (who is to receive the title and style of HRH Prince of Romania on his 25th birthday this year)
4.Elisabeta Karina de Roumanie
5.HRH The Princess Irina of Romania
6.Michael de Roumanie Kreuger
7.Angelica de Roumanie Kreuger
8.HRH The Princess Sophie of Romania
9.Elisabeta Marie Biarneix
10.HRH The Princess Marie of Romania
An interesting addition, thank you.
