Bo 1

It has never been used as a female name in Scandinavian countries. It is strictly a male name in Scandinavia.

Scandinavia, which, most commonly refers to Denmark, Norway, and Sweden, can, in certain contexts, also refer to the Scandinavian Peninsula, which (excluding Denmark), includes part of northern Finland.

Based on their ethnolinguistic relations with Denmark, Norway, and Sweden, within this context, also include Iceland and the Faroe Islands.

Bo is also used for females and would certainly qualify as unisex. The pronunciation for this name is equally appealing (as is its meaning). It has both strong and delicate qualities. Within Scandinavian countries and North America, it's been traditionally used more for boys, but has also taken an interest for girls as a given, middle name, or short form, and been particularly popular within the Netherlands and Belgium.

Alternatively, though traditionally male as well, the older Scandinavian versions Bó and Boe would also work.

Also short for Beauregard or any name beginning with the sound Bo.

Bo for a girl? No way!.. It's okay for a boy only.

In Denmark we would ONLY use this on a boy. Some names just only works on one gender.

It's a girl's name too. It is my mother's friend's name. I think it is a good name, but I shall never name my son this as I feel that it is very feminine.

This is also a Dutch name, my cousin bears this name too. It is an ordinary name in the Netherlands, but not very common.
