Abraham is my 99th great grandfather.
His son by Hagar, Ishmael, is my 98th great-grandfather.
Ishmael's son Massa bics my 97th great grandfather.
I have heard that The tribe of Massa settled in what is now Yemen, which makes perfect sense, as the kings and queens of Sheba founded the nation of Yemen.
I believe the civilized half of Yemen -- that half not taken over by the Houthis -- is the land once called Saba or Sheba.
