I found an article on Barbie's history of family and friends. I grew up playing with Barbie in the 80's and find it interesting that my nieces are still playing with Barbie Dolls 20 years later.

(Lois Lane doll)

Here is what we know about Barbie's family tree from the article:

Barbie was born in 1959
Skipper was Barbie's first sister born in 1964
Twin siblings were born in 1966 - Tutti and Todd
Stacie, an unexpected surprise sister, was born in 1992
And another sister, Kelly, was born in 1995

Barbie has 2 known cousins:

Francie born in 1966
Jazzie born in 1989

What do we think genealogists, enough clues here to find out who Barbie's parents are? What about grandparents? We've got some work to do. :)
