I was born in 1980 and Joanne was by far the most popular name when I was at school. There were 3 in my tutor group and 9 in the whole year. As a 44 year old woman I have lots of friends, colleagues, acquaintances called Jo.
Sorry - I think it’s such a dated and boring name. I think people will be shocked to hear a little girl named Joanne in 2024.
