La Familia Feliz is a line of dolls and accessories sold by the Congost company of Spain. The line was created in the mid 1970s by Mattel and marketed in English as The Sunshine Family which Mattel eventually changed to The Sunshine Fun Family. Later the family of three was given a slight cosmetic makeover and the addition of a new baby, making them four, plus a Grandmother and Grandfather doll. Mattel also created an Afro-Caribbean family along with Afro-Caribbean grandparents.
