I took another look, following my own advice. I see that Samuel (carter-42381) is only about one or 12 years, depending on which birth date of Shadrach you use, older than Shadrach (carter-36380), so he can't be the father.
Once you sort out who belongs where, or even that someone DOESN'T belong somewhere, you can go into the Edit tab, locate, in this case, the father on the upper right, and click on remove/replace. This doesn't destroy the profile; it simply unlinks the two you're working with. Then you might want write a very brief note in the text, somewhere, maybe under Research Notes, that you did this and why.
Hope that helps.
