I rode a lot of threads ,etc about them.I came to a conclusion .They aren't siblings.Mikasa kept the surname,and if you adopte someone ,you must change their surname,also Ackermans were hated so what's the point on letting an Ackerman alive(for those who hated them).Btw no one know where Ackermans lived,Mr Yaeger came there for medical visits or something like that.Even Mikasa reffered to them as Mr.Yaeger and Mrs.Yaeger.They never reffered to each other to brother and sister,even Eren said that he isn't her brother or son.Something it's obvoius 100%,Mikasa has romantically feelings for him(can't deny that) she always blushed when Eren was involved and she always listened to his tips(i don't think a sister  will always be blushed when your brother it's involved.She even understood his order to not babysit anymore like a useless boy ,and to have trust him,but she also protects him.And for damn thing as I sais about her ''adoptation",Yaegar was a doctor with extra business things who wouldn't risky an Ackerman to adopt her.There're a lot of hints Isayama gave us.
