Letizia is already listed as "Novità" in the 1996-97 Barni Catalogue page 5: Letizia (Kordes 1996) Bartizia. However the 2013-14 Barni Catalogue page 13 reports a different year: Letizia (Kordes 1998) Bartizia.
This is what I understand. A similar thing happened with Emozione (BARemoz bred by Kordes) as stated in Barni catalogues. Probably the two firms had some mutually convenient agreement.
