Francizska is her middle name. Her mum was Polish or of Polish origin, that's the reason why. I guess that, like Holly Gabrielle, she chose her middle name as her "brand" or "influencer name" instead of her surname for privacy reasons. I was very hooked by her content as well. She was always very open about mental health, and I remember she made a live Q&A on YT once where she even answered a couple of my questions regarding depression and BPD. In a couple of videos she mentioned that she wanted to become a lawyer, hence her law course, but she always mentioned that while looking for trainee contracts she wanted to pursue a Masters in Literature. Ibz Mo did something similar, he finished his law course and then studied a Masters in Education in Oxford, I guess to cultivate themselves but still, those are very expensive courses taking into consideration they will be of no use in their future legal careers.
EDIT: PS. I also miss her content, I hope she's well.
