The same year, the most popular male names were: John, William, James, Robert, Joseph, Charles, George, Edward, Frank and Thomas.Both locally and nationally, this year's most popular names have clear ties to pop culture.Mason, the most popular boys' name in 2016 is also the name of reality star Kourtney Kardashian's son.The name first appeared on national popularity lists a year after his birth and debut on "Keeping Up with the Kardashians."Emma, which ranks #1 in the region and #2 nationally, appeared on popularity lists for the first time in 2002, the same year Jennifer Anniston's character on "Friends" gave birth to a baby girl who she named Emma.While "Friends" aired its series finale in 2004, the name's continued popularity likely is because of Harry Potter's leading actress, Emma Watson.Liam has been popular nationally for the past three years, coinciding with the pop music reign of boy band One Direction and their member turned solo star, Liam Payne.A newcomer to the list, Alexander, may have been influenced by the wildly popular Broadway musical "Hamilton," about the nation's founding father, Alexander Hamilton.Isabella and Ella round out the remaining top three female names in the area.While Isabella has been popular nationally for the past decade, the Lehigh Valley may be leading a trend with the shortened variation, as Ella has not yet appeared in the top five nationally.
