Betsy is an English pet form of Elizabeth, the Hebrew Elisheva, which means "my God is an oath" or "God is abundance". In America it is tied to Betsy Ross, the Philadelphia seamstress credited with sewing the first stars-and-stripes flag. The name returned to the top 1,000 in 2006 and peaked at number 747 that year, but has slipped since and ranks number 2,724 in 2025, with 63 births.
