First appearance
1914
The first year at least five boys were named Cosby! It came in at #2,651, and was given to 7 baby boys.
Quietest stretch: 1916, when fewer than 5 boys a year got the name.
Where Cosby is popular in 2025
No state had 5 or more boys named Cosby in 2025, so the SSA doesn't publish it for any state.
