After nine attempts to breed a stable clone of the Princess of Alderaan under the designations LV-alpha-1 to LV-alpha-9 had failed, Vader started looking for alternatives. He finally ordered the Kaminoan cloners to use material of a Jedi Padawan, Minafe Felis, who had died by his own hand during Operation: Knightfall in the Jedi Temple in 19 BBY. The genetic sample had been collected from her, as secretly done with every Jedi Initiate at Chancellor Palpatine's command, when the young Witch of Dathomir had been inducted into the Jedi Order some decades earlier.
