From previous answers on the same subject, i was told you can grant levels from a charactor which has been granted levels, i.e. if you use your level 60 to grant 30 levels to your level 1, then that level 1 (now a loevel 30) can grant 15 levels to another level one linked to a toon which it was referred from.
The key is that you can only grant levels to the account which referred that account, you cannot grant levels from the old account to the new account.
I have not granted levels from an account which has been leveled using only granted levels but in another thread which I created I was told it was possible.
