Was that determined by DNA? When you say you went from a Sayers to a Howell, was that mentally or did we go back and start changing names based on sources. If it were considered a NPE your Grandpa would no doubt, be considered a Howell. Throw in (sources) a marriage license and birth certificate, now he's a Sayers. Throw in (more sources) DNA, now we have a conundrum. For the sake of accuracy, should a NPE be documented within marriages when they are proven to exist? I'm sure this has occurred more than twice in human history. Regardless, you are still one of my favorite Wiki cousins even if the Sayers/Howell dynamic changes our relationship.
