I'm afraid the bad news is, your ancestors aren't yours. A wrong turning's been taken. We've all done it at one time or another.
Alice was only 27 when William Henry got married, so she wasn't his mother. She was the mother of a younger William H.
So basically William H needs splitting into two profiles.
The older one gets the DoB, the wife, and the kids, but no bio or sources yet.
The younger one gets the parents and all the bio and sources.
Then you can leave the younger one aside and look for the parents of the older one.
