Maybe it's the influence of British royalty or a popular children's character.
Whatever the reason, babies born at Greater Baltimore Medical Center last year were most likely to be named William or Olivia.
The hospital released its annual report of popular baby names Thursday and found that 35 parents named their baby boys William and 35 others named their girls Olivia.
Doctors at the hospital delivered 4,057 babies in 2012.
Eight new baby names entered the top ten list for the first time. Four were girl names: Harper, Lily, Lillian and Riley. Four were boy names: Blake Caleb, Henry and Wyatt.
Olivia was the most popular name for the third year in a row. William was the most popular in 2008 and 2009.
