Help!

Hi! So I’m looking for a particular anime which I only remember vaguely about. I’ve watched this anime anywhere between 2005-2010 it’s an old anime. It’s set in a Victorian age and the lead girl has blond hair. I’ll just tell you what I remember about the plot; i think the lead girl was an orphan and she got switched at birth, she was originally a nobleman’s daughter. She reached a certain age and went out exploring the world, i think she was trying to find her family?? The only thing I remember is that she was in Egypt and there were 2 men chasing after her either to kidnap or kill her because it was their mission. One way or another they got trapped inside a pyramid and the lead girl had an orange, the guys wanted to fight her for it because they were really thirsty but she still willingly shared it eventhough they were her enemy. Time skip, she met the girl dhe got switched with during birth ( but she doesn’t know that) they ended up being friends and stuff. And there was this guy who always mysteriously showed up around the lead girl, i think he knew about her true identity. I’m so sorry about so little details, but if you have any ideas pls help me!
