"Variant of Jacqueline"
The name Yaquelin is commonly a female name from the "French" origin.
Yaquelin is a Spanish-language variant of Jacqueline, the French feminine form of Jacques, itself a form of Jacob. The initial Y- represents the Spanish spelling of the French J- sound, matching other Spanish forms of the name such as Yaqueline and Yacqueline, and the ending -in follows the same pattern. The name is attested in Spanish-speaking countries and began appearing in United States birth records in 1980.
Jacqueline means "To protect".
The pronunciation of Yaquelin is yah-keh-LEEN.
