Meaning and history
Mabel is a medieval form of Amabilis. Mabel and Amabel were common in the Middle Ages but rare after the 15th century, then revived in the 19th, perhaps helped by characters bearing both forms in C. M. Yonge's popular novel The Heir of Redclyffe (1853).
Mabel rose from #222 to #201 for girls between 2024 and 2025. Its highest annual birth count came in 1915, with 3,683 births.
