Jonpaul is of American origin, derived from the blend of Jon and Paul. It gained popularity as an independent given name in the mid-20th century.
The name Jonpaul experienced its peak popularity between the late 1970s and mid-1980s, with over 40 births per year occurring between 1976 and 1985, peaking at 67 births in 1979. However, there has been a significant decline since then, with fewer than 30 births per year from the early 1990s onwards, and only single-digit numbers from 2009 to present, indicating that it is now quite uncommon.
