please help :,)

I read a book in like middle school, and idk What this “trope” is called but it was like, a warrior finds an abandoned little boy ( may have killed the kids parents) and the warrior raises the boy so on and so forth, I can’t seem to find any books like that or find what that kind of trope is called ( would be preferred if it could be a fantasy book of some kind )

Thanks you so much in advance <3<3
