"Variant of Jacqueline"
The name Jacquelina is commonly a female name from the "French" origin.
Jacquelina is a variant of Jacqueline, the French feminine form of Jacques, which is the French form of James and goes back to the Hebrew name Ya'aqov. The final -a gives it the shape of feminine forms found in Spanish, Portuguese and Italian. It shares the root of Jacqueline rather than having a separate etymology of its own.
Jacqueline means "To protect".
The pronunciation of Jacquelina is jak-uh-LEE-nuh.
