According to our sources at Ancestry.com (currently worked by her nephew James) when Cristine Louise Kleiber was born in 1950, her father, Charles, was 33, and her mother, Loretta, was 30. She married Kenny Selvia in 1987 and has one brother (Charles Joseph) and one sister (Margaret Ann).
Christine often says that being the middle child is the hardest one to be, since all the attention goes to the oldest and youngest in most families. Looking at her childhood pictures she may have a point as it seems that there is a Peg or a Mark in almost every picture with her. As she got older, it seems she began sharing the photo spotlight with her little brother. Criss also says her dad wanted a boy so she grew up a bit of a tomboy as a child.
Another thing she often said was that her dad wanted a boy and would buy her things a boy would like, trying to turn her into a tom boy, looking at the picture of her dressed with cowboy guns and holsters you have to give her the benefit of the doubt on that as well.
