Isaac, like many other male Biblical names, has been rather popular in the U.S. in recent years. It entered the Top 100 in 1995, at #98, and has been in the Top 50 since 2001. Its most popular ranking to date came in 2013, when it was #29. Isaac has held steadily at #31 ever since.
The name is also very popular in Canada (#24), Australia (#14), England and Wales (#20), Mexico (#42), New Zealand (#30), Portugal (#40), Northern Ireland (a.k.a. Ireland by any other name) (#42), Scotland (#54), and Catalonia (#56). It’s additionally in the Top 100 in Spain (#82), France (#70), Chile (#70), and Ireland (#77).
Though my favourite of the Biblical Patriarchs is Jakob, I have a soft spot for Isaac. He’s kind of The Quiet One of the three Patriarchs, since he’s always passively acted on instead of acting in his own right, or copying things that already happened to his father (e.g., passing his wife off as his sister in Egypt, uncovering wells his father had dug).
Isaac means “to laugh,” from the Hebrew root tzachak. It was mostly a Jewish name in the English-speaking world until the Protestant Reformation. Famous bearers just about everyone has heard of were Sir Isaac Newton and the awesome writer Isaac Asimov.
