Newly fashioned but familiar and with an on trend, unisex feel, Addison seems like the perfect solution for anyone who can’t decide between Madison, Adeline, and Alison. 
Addison really took off in the mid-2000’s, making a spectacular jump from being outside the Top 100, to being nearly within the Top 10, just two years later. Undoubtedly influenced by the introduction of Dr. Addison Shephard to “Grey’s Anatomy”, the name was at its peak in 2009. 
While it’s been steadily falling back down the charts, it does remain a popular choice. Currently given to nearly 4000 girls in the US each year, it ranks highly in New Zealand and Canada too. In the UK, it has made significant gains, becoming familiar for girls – and for boys too. 
Borrowed from an English surname, meaning “son of Adam,” Addison joined Madison as one of the few “son of” names to be used almost exclusively on girls. It also joins the 17 strong crowd of “Ad- names” in the charts for girls, including Adeline, Adelyn, and Adelaide. 
Contemporary and cool with a cute, sassy nickname, Addison has been a popular choice for celebrities. Baseball player Jason Bay, TV personality DeAnna Papas Stagliano, NASCAR driver Sam Hornish Jr, and Joe and Kendra Duggar all have daughters called Addison. 
It is unclear if Addison will fall as fast as it rose, but for now it remains comfortably within the Top 100. So, if love Addison but want your choice to stand out, you could try: Sullivan “Sunny”; Halliday “Hallie”; Barrett “Betty”; or Alcott “Lottie.”

Maisie, a charming name long popular as a nickname for Margaret or Mary, entered the Top 1000 as itself ten years ago and continues to rise. Game of Thrones star Maisie Williams helped propel the name back into the limelight, along with the that of her character, Arya.

In literature, Maisie is the name of the precocious young title character in the Henry James novel What Maisie Knew, and is also the main female character in Rudyard Kipling's The Light That Failed. And to bring things up to date, Maisie is a half-blood character in the Harry Potter series. Spelled Maisy, it's a popular children's book series.
 When Maisie re-entered the US Top 1000 in 2014 at 658, it was one of the fastest rising names of that year. She's still got a ways to go In the US to catch up to other English-speaking countries, where Maisie ranks in the Top 100.
