I am a genealogist working for a family who has a Rosita Felis. The Maria Rosario Felis I am working on I know her end result however I believe she maybe possible the one linked to Joaquin Murrieta or maybe not.
I have read the other name she used was Ana la Molinera and left Joaquin Murrieta for Pancho Daniel his Commander. This left Joaquin very upset and set men to kill her. He sent a man name Vergara to kill her. Vergara deserted and then left eventually to Sonora.
If you have more info e-mail me.
