DREXEL HILL — A woman gave birth to a more than 13-pound baby Monday at a southeastern Pennsylvania hospital.

Officials at Delaware County Memorial Hospital say Brian and Danielle Dwyer’s son is the largest baby they can recall born there.

Waldo James Mysterious Dwyer tipped the scales at 13 pounds, 8½ ounces.

The couple loved the “Where’s Waldo?” books as children, so that’s where they got their son’s name.

Brian Dwyer said the middle name Mysterious is because Waldo was born under a lunar eclipse on April 14, 2014 — a date that reads the same forward and backward.

The Dwyers live in the Fishtown section of Philadelphia. New dad Brian is a co-owner of Pizza Brain, a popular pizza shop and pizza museum.
