The Plant lines studied are just those of amateur genealogists who have
traced themselves back typically to around 1800, sometimes further. In one
case, the finding that a Plant did not match the main Plant family
reinforced the idea that his surname traced back to an IGI record for an
unmarried mother.

For documentation on FPEs, a Google Scholar search on "non paternity
events" brings up a lot.
