@only1bob,
At some point, your daughter would have to realize that the jig is up. I think she's more angry at you for figuring it out and facilitating the revelation versus there being a revelation in the first place. At least, I would hope that to be the case.
Family secrets such as these are a lot harder to keep these days, as opposed to a generation ago or even ten or so years ago. Easy access to DNA testing can bring with it some uncomfortable revelations.
So, maybe give your wife and daughter some grace and some time to process all of this. You brought the truth out. It would have come out sooner or later. Now, maybe your family can start to embrace the new reality and move forward.
