Does anyone here know what the origin of the name Anna Rosina Decker would be? I have heard both Columbian and German, and now possibly Italian! Vastly different, I know. The woman in question was slightly dark-skinned and had extremely dark hair, possibly indicative of some Latin or Italian heritage of some sort, as is the name Anna Rosina. I may be WAY off here, and I apologize if I am, but if anyone could help me out here it would be so greatly appreciated! Thanks in advance!!
