Much to my surprise, "Aleksandr[i]a Alicja" ("Alexandr[i]a Alice") was and is a more-common name than I thought. I figured that it was mostly a family name. So, who was the original "Aleksandr[i]a Alicja"? Was she a Roman Catholic saint or Polish heroine?
Both Aleksandra and Alicja are very popular Polish given names. Children are typically given two names at the christening, so the chances of coming across an Aleksandra Alicja are quite high statistically. No, there was no famous historical figure called Aleksandra Alicja.
