Well, since Gotra is decided paternal side that too of Father then I don't think there is issue with it. Here Grandmother of Boy, there is no direct link of Gotra with his father. I have a friend who is expert in these matter as he qualified astronomer and religious preacher, I will also confirm with it though.

Just remind me here.
