[Theodore R.]

Does Winthrop Paul Rockefeller have seven children? Are they by the same wife?

[Verginius Rufus]

According to Who's Who he has seven children--Andrea, Katherine, Winthrop Jr., William, Colin, John, Louis. The entry notes only one marriage, to Lisenne Rockefeller (no date of marriage given), so presumably all of the children are of the one marriage.
