Would someone happen to have a list of Jagiellonians?
Your post is a bit unclear. The list of Jagiellonian kings in Poland is readily available in Wikipedia or elswhere. This surname in Polish is "Jagiełło" and apart from being the name of the first Polish-Lithuanian king (Władysław Jagiełło), it is an ordinary family name in Poland these days, by no means asocciated with the royal name of the Jagiellonian dynasty or a noble name of any kind.
Władysław (Ladislas) is a common Christian name in Poland, not at all popular among the younger generarations these days, but it used to be a very popular Polish Christian name in the past. The kings who also bore this name were: Władysław Herman, Władysław £okietek (of the Piast dynasty), Władysław Warneńczyk (od the Jagiellonian dynasty, son of Władysław Jagiełło), Władysław IV (of the Vasa dynasty)
