Trey's mother, "Dina", was a writer/editor for Sesame Street Magazine. She has written a number of children's books, mostly published in Ireland. They wrote stories and songs together, and put out at least three albums together: Quentin the Quackless Duck, Timothy Tatter's Sad Gloomy Day, and Large Motor Skills. More recently (circa 1995?), Dina wrote a book to accompany a television series, Virtual Reality Rangers. She's also done some work for the Sesame Street website, including "Make your own lunchbox".

In the the Sept '96 issue of Sesame Street Magazine (p.19, shown above; click for larger image), the Count is counting to nine, nine fish doing various activities. There's one fish playing with alphabet blocks, making a tower. On the top, the little fish spells out FISH. On the bottom is spelled out TREY. And there's a suspicious character near the bottom left playing a Languedoc! (Special thanks to Chris M. Thiede 9/13/96 and Paul B. Roth.)
