Beyonce Giselle Knowles was born in Houston, Texas, to Celestine Ann "Tina" Knowles (nee Beyince), a hairdresser and salon owner, and Mathew Knowles, a Xerox sales manager. Beyonce's name is a tribute to her mother's maiden name. Beyonce's younger sister Solange is also a singer and a former member of Destiny's Child. Mathew is African-American, while Tina is of Louisiana Creole descent (with African, Native American, French, Cajun, and distant Irish and Spanish ancestry). Through her mother, Beyonce is a descendant of Acadian leader Joseph Broussard. She was raised in a Methodist household.
