Africa's Richest Woman

MIght be a nothin' burger, but Isabell dos Santos is from a former colony of Portugal in Africa (Angola).

So is Theresa Heinz Kerry (Maria Teresa Thierstein Simões-Ferreira), albeit from a different former colony (Mozambique).

Going back in history, makes me think of Portuguese Henry the Navigator, who initiated the Age of Discovery.

"On 25 May 1420, Henry gained appointment as the Grand Master of the Military Order of Christ, the Portuguese successor to the KNIGHTS TEMPLAR, which had its headquarters at Tomar, in central Portugal.[5] Henry held this position for the remainder of his life, and the Order was an important source of funds for Henry's ambitious plans"
