Not so much barf as guffaw
Probably get a mix of both.
I took 3 different DNA tests. All came back with different results.
Ancestry 100% European
Family Tree DNA 99% European 1% unknown
23&Me 89% European 10% Nigerian???? (WTH?) 1% Pacific Islander. 23&Me said my GGGGGGrandfather was 100% Nigerian?????
I’ll bet E Warren used 23&Me.
23&Me makes up results. They are SJW.
I took so many tests because I was adopted. I did find my birth families through Ancestry.Com
