BS!
I have proof that MY family wasn’t even HERE until the 20’s..
MY people were in Turkey getting the s^&%$ kicked out of THEM and WORSE ... while these guys got free and failed to overcome THEIR less than ideal start in life here in the US AND then failed/refused to assimilate at LEAST enough to capitalize on THEIR freedom!!
I would guess that a very large majority of white, Hispanic, and Asian Americans trace their American roots to sometime AFTER the Civil War, and in millions of cases to after WWII.
