The top middle names for baby boys and girls over the last century are a more stable group than first names, which go in and out of fashion more dramatically and rapidly. The most common middle names, on the other hand, often honor family members or provide a smooth bridge between first and last names, so they're a less diverse group.
For girls, the top middle names of the last hundred years are Marie, Ann (and Anne), and Elizabeth. For boys, Michael ranks as the top middle name of the century, followed by Joseph, William, and James.
Girl middle names popular in the first half of the 20th century that later faded away include Irene, Mae and May, and Ruth. After 1950, middle names for girls that rose to prominence include Kay, Sue, and Renee. After the year 2000, Rose, Grace, and Faith became popular middle names for girls.
For boys, middle names popular before 1950 include Henry, Francis, and Eugene. After 1950, Lee, Ray, and Wayne came into use. Lee remained popular as a middle name for boys after the year 2000, when Alexander and Matthew also came into play.
