Adalyn

Adele and Adelaide became widely used through the influence of Saint Adelaide of Italy (931-999), Holy Roman Empress, wife of Otto I, who was canonized in 1097 by Pope Urban II.

Her granddaughter and the many subsequent noblewomen bearing variants of the name spread it across France, Germany, and England.

The diminutive Adeline appears in Norman French records from the 11th century and was introduced to England after the Conquest of 1066.

The English poet Alfred, Lord Tennyson wrote Adeline (1830), and the French song Sweet Adeline (1903), composed by Harry Armstrong with lyrics by Richard Gerard, became a barbershop quartet standard and later the namesake of the Sweet Adelines

International singing organization founded in 1945.

The name declined through much of the 20th century before returning emphatically in the 2000s.

The spelling Adalyn is a distinctly American 21st century creation, part of a broader trend of respelling classic names with -lyn endings to create fresh visual identity, seen also in Madelyn, Evelyn, and Katelyn. According to U.S.

Social Security Administration records, Adalyn first entered the top 1000 in 2008 and climbed sharply, breaking into the top 200 within a decade. The variant Adalynn appears alongside it, sometimes ranking even higher.

The name remains predominantly an American phenomenon, with the traditional spellings Adeline and Adelaide preferred in the United Kingdom, France, and Australia.
