Something I don't see mentioned, isn't our idea of beauty supposed to be heavily influenced by our immediate family? So if we're painting random beautiful people in the background, it wouldn't be surprising that they're loosely based on our family members who would have traits very similar to ours. Further, with something like the Sofonisba Anguissola self portrait, the virgin Mary being influenced by her mother would explain everything just as well. Even the similar hairstyle could be her copying her mother rather than inserting herself as Mary.
