Molly

Molly is a diminutive of Mary, the ancient Hebrew name Miriam, whose meaning is debated but often given as "sea of bitterness," "wished-for child," or "rebellion." In practice, Molly long ago shed any of that weight. In Irish folk culture especially, Molly became a term of endearment, a warm and spirited name with a lilt that makes it feel instantly friendly.

Molly ranks #22 among the most popular US pet names, with over 2,600 companions sharing it. It is one of those names that has been beloved for so long it feels like part of the furniture — and yet it never becomes stale. Molly suits companions who are social, expressive, and just a little theatrical about their affection. The name has particularly strong associations with warmhearted, people-oriented animals who know exactly how to win a room.
