Seems legit.
Not exactly. Probably written by someone who believes in Climate Change and knows that San Francisco will be flooded before the end of the Trump Administration
This group is one of the four major Native American groups in North America. These groups are traced back to four female ancestors: Ai, Ina, Chie and Sachi. Crawford appears to be a descendant of Ina.
This part is mostly nonsense. No such women named Ai, Ina, Chie, and Sachi existed. A mathematical extrapolation for mDNA was examined to determine the earliest ancestor for the haplogroups for Native Americans. Crawford shares the haplogroup with the mythical Ina, but it doesn't mean much more. He probably has some Neaderthal DNA also, but we're not sure because Ug did not leave a will.
