Chimerism can sometimes split families. Lydia Fairchild submitted a child support application in 2002. But DNA tests revealed that she was not connected to her children. Fortunately, she was identified as a chimera; else, she would have lost her children.

During the case, she became pregnant with her third child, who still had different DNA while in the womb. Even though a judge had arranged for a witness to be present at her third child’s birth, the courts prioritized her DNA tests over her doctor’s testimony.
