Sorry joggy I've been busy doing someone's tree so have tried not to get involved in posts on here.
I don't think there's anything you can do about the credits on GR as it will be hidden somewhere in their T&C's.
I find the best way to check on ancestors with similar names is, if possible, by their wedding certificates, as you get 2 father's names for the price of one.
If you would care to give what details you have I will check on-line for a possible parish record e.g. banns for a father's name.
