>>20223569Now seriously, wether a woman can be queen or not depends on the laws of the country, which may or may not state that men have priority over women regardless of age.
That said, a queen can be so either by marriage or on her own right. A queen that is daughter of the previous monarchs is queen by her own right , but if she's only related to the royal family by being married to the throne's inheritor she is Queen by marriage, since she didn't truly inherited the throne, her husband did.
Get your facts straight yo.
