People often say that all of Trump's children are married to Jews, but I read on DailyMail that Don Jr and Vanessa are Catholic. That does not seem accurate—I haven't found any evidence online of Catholic church attendance, for instance. They were married at Mar-a-Lago by his Aunt Maryanne Trump Barry, the judge, so no priest and no church. Wikipedia says Vanessa has Danish heritage as well as Jewish, and photos show she did wear a cross at their wedding, so maybe the Christmas cookies are a real thing for them:
So I was wondering if their having five children is a result of Catholic proscriptions about birth control, but again, hard to tell, since they are wealthy enough to support as many children as they want. Gorgeous wedding dress, by the way.
At any rate, Trump has both Jewish and Christian family members and grandchildren of both faiths.
