I would need more information about your CHILD's roots. As far as I'm concerned, I have no such people in my genealogy BUT I'can't tell you that I have drawn ALL my family members. You should go and have a look to this website (The Mormonts): www.familysearch.org.
I have mylself made very funny and surprising discoveries about my CHILD family. Be patience 'cause CHILD is a very common name in UK; all Childs doesn't belong to the same tribe. Of course I can help you if you have questions about particular people.
