Blaine is a unisex given name of French origin, derived from the French word 'blanc', meaning 'white'. It gained popularity as a boy's name in the United States during the mid-20th century, likely due to its similarity to other popular names of the time like Brian and Blair. The name Blaine can also be found in English literature, notably as the main character in James Fenimore Cooper's novel 'The Last of the Mohicans'. However, it is important to note that Blaine has been used as a given name for individuals of both sexes throughout history.
The name Blan was consistently popular during the early to mid-20th century, with a noticeable peak in usage between 1921 and 1922, followed by another spike in 1947. However, there appears to be a significant gap in its popularity between 1922 and 1943, as no births were recorded during this period. Overall, Blan was given to a total of 22 newborns across these years.
