Andrew Taylor, whose "Petra FAQ" was the original source of a great deal of this information, says: "The info came from the Tenth Anniversary Petra Songbook which included photos from the 'More Power To Ya' Tour. Other info came from (I think) the April 1994 issue of CCM. The ages of any children listed are what they were in April 1994." [NOTE: ages you see on this site should be accurate to within one year; in most cases they will be exactly correct]

Amy Bonner also wrote with some information: "All of this information comes from the On Fire! Songbook, the Battle Plan Volume 8, Number 1 for Spring/Summer '91, the Battle Plan Volume 9, Number 1 for Spring/Summer '92, the Battle Plan Volume 10, Number 1 for Fall/Winter 1993, and the April 1994 edition of CCM." (She gave some age listings too; they also generally fall in the neighborhood of 1993-94.)
