Re Malia Cohen, I did a little digging. Her grandfather had the absolutely priceless name "Bishop Cohen" (https://casetext.com/case/cohen-v-cohen-in-re-estate-of-cohen). He was a longshoreman from Galveston. His own father was Frank Cohen, a farmer originally from Alabama. When he died in Galveston in 1939, his widow named his father as "Henry Cohen," but wasn't sure where he was born. We can find Henry in the 1880 Federal Census, a Coffeeville, Alabama laborer (probably in a sawmill).
Henry is listed as a "mulatto" born in Alabama in 1845, so it's at least possible his father was a white slaveholder. You can find an online family tree connecting Henry to the family of Solomon Cohen, a prominent Jewish South Carolingian, but based on five minutes of review and several years of experience, there are serious problems with this family tree. But--great family to do a Y-DNA test on! If you get a common Jewish haplogroup or even the "Cohen modal haplotype," you've got a compelling clue.
