    His father’s non-Irish ancestry is one eighth.

    This says that Mary Ellen Goonan’s parents were John Goonan and Mary.

    Most Americans tend to be “remote Dutch” for some reason.

    • AutisticApe says:

      Because most Americans with colonial/mostly colonial roots tend to have remote/distant Dutch ancestry due to the fact that the Dutch had a colony called New Netherland, which included modern day New York and New Jersey. After the English took over the colony, the descendants of these Dutch colonists gradually moved away from their ancestors’ culture and married into the predominantly Anglo population.
