These are the things I remember: The main character was a young London boy, not sure who he was being raised by. Either his parents or aunts? Two men showed up and robbed the home, the boy was told to hide in cabinet or closet under rags/towels. He was taken (not sure what happened to the adults but I think they were killed.) He gets taken to a mansion and made into a butler or something. The staff would only let him eat scraps. Eventually he finds out the nice old man who owned the mansion was in fact his grandfather. I I read this book in elementary. I know it’s not Oliver Twist, but most people guess it is.
