1952, My South African Mother fell in love with Mormon missionaries in Bloemfontein & consequently ended up marrying into the Mormon Young clan. Turns out, 23 & Me tested mother as 5% Sub-Saharan Black African. My father is Brigham Young Jr’s great-great Grandson. I was rather amused to read Brigham’s 1852 speech; from the pulpit, in The Tabernacle.. “Not 1 Drop” of Negro blood, or else! When I get to heaven, it could be interesting to determine what neighborhood I spend eternity in.
I haven't read much about Clark. I would be interested to learn more, particularly about his views (as stated in this discussion) about Jews. Did he, e.g., view Jews as a sub-racial group? Or did he, like many people do today, hold a critical view of Jews not because of race or religion, but in the context of their political activity.
