The story of Millie
Millie started out as a short form, with the familiar -ie ending, of several longer names: Mildred, Millicent, Emily, Amelia and Camilla among them. Because it grew from so many names, it has no single meaning of its own. Today it is usually given as a full name rather than a nickname.
In Ireland Millie first appears in the CSO records in 1999. It climbed through the 2000s and 2010s and reached number 19 in 2022, when 206 girls were given the name. It has eased back a little since.
It is less common in Northern Ireland, where its best position was 76th, also in 2022.
