Yes, she still belong to the house and the family. But it depends on the court protocol which rank they are going have. I think the japanese court dismiss the female children from royalty (losing their titles, privileges) when they are going to marry a man. In other courts they keep them. But I'm not an expert in asian courts.
At least the europeen nobles are all related over the edges and they help each other more or less. Which means for example the german high nobles, who have lost all their ranks and titles, when germany became a republic, are still connect to other kingdoms and invited to social events, like wedding or new marriages. The ex-emperor, which we have thrown out, found an exile in the nederland with an invitation of the king (or queen?) then, but he was forced to live on one place and wasn't allowed to move more than 15 km away from his house.
