Hi Christine,
You have not linked your father to your profile here in WT. If he has a profile here, is the info incorrect here in WT. If so, you can contact the profile manager and work with them by supplying proof of the corrections.
You will have to upgrade your profile to member, it's free.
If you are talking about other websites, such as Ancestry, every instance of your father is separate, and people notoriously accept any hint without research or thought. Since your last name is pretty common, this could lead to much incorrect information.
What I do is try to get everything correct here, with sources, and if I do fill anything out on another site such as Ancestry, I be careful to make sure not to accept incorrect information hints.
Rick
