Boise is of French origin, meaning 'wooded'. It's predominantly used as a masculine given name, though it can also serve as a surname. The name gained prominence in the United States due to the city of Boise, Idaho, which was named after the French-speaking explorer and fur trader François Payette, who arrived at the area in 1824.
"The name Boise was popular around the early to mid-20th century, with peaks in 1921 and 1926, but has since seen fewer occurrences."
