Meaning & origin
Seanna first appeared in U.S. birth records in 1959, but its use grew slowly over the following decades. It reached its highest popularity in 2006, when the name peaked and began a gradual decline. By 2025, the name had fallen to a rank of 5,238, with roughly 1 in 66,969 newborn girls receiving the name. The trajectory shows a consistent drop since 2006. Seanna is most commonly found in California, and its spelling reflects a modern adaptation of the traditional Irish Séanna. While never a common choice, it carries a soft, melodic sound that appeals to parents seeking a variant of the classic John lineage.
Seanna is an Anglicized spelling of Irish Séanna, a variant of Seán (John), derived from the Hebrew name Yochanan meaning 'God is gracious'. While the traditional Irish form has long been used in Ireland, the spelling Seanna emerged more recently in the United States as a feminine form, influenced by similar-sounding names like Sianna or Shawna.
