Santorum and his wife, Karen Garver Santorum, have six children: Elizabeth Anne (born 1991); Richard John ("Johnny"), Jr. (born 1993); Daniel James (born 1995); Sarah Maria (born 1998); Peter Kenneth (born 1999); and Patrick Francis (born 2001). In 1996, their son Gabriel Michael was born prematurely and lived for only two hours (a sonogram taken before Gabriel was born revealed that his posterior urethral valve was closed and that the prognosis for his survival was therefore poor). Karen Santorum wrote a book about the experience: Letters to Gabriel: The True Story of Gabriel Michael Santorum. In it, she writes that the couple brought the deceased infant home from the hospital and introduced the dead child to their living children as "your brother Gabriel" and slept with the body overnight before returning him to the hospital. The anecdote was also written about by Michael Sokolove in a 2005 New York Times magazine story on Santorum. Karen is also the author of a book on etiquette for children.
