Bettylou

Bettylou is a feminine compound name that combines two classic American names: Betty (traditionally a diminutive of Elizabeth) and Lou (which can be short for Louise or Louis). Popular primarily in mid-20th century America, Bettylou represents the trend of hyphenated or combined names that emerged during that era. It evokes a nostalgic, Southern charm and was most common in rural American communities between the 1930s-1950s. While Betty peaked in popularity during the 1930s, the combined form Bettylou never achieved the same widespread usage. Today, it has a distinctly vintage quality, occasionally experiencing small revivals among parents drawn to retro Americana names.

Pronounced BET-ee-loo.

As of October 2026, Bettylou ranked #14796 for girls in US births in 2015 SSA, peaked at #811 for girls in 1927.
