Abram was Abraham's original name in the Bible; it's more user-friendly but with a bit less gravitas. And it does offer that cool nickname Bram, as well as the friendly Abe. After some early American usage, in 1936 Abram completely disappeared for nearly forty years, until its return in the 1970s.
Abram has experienced its greatest popularity in the past decade, making its way to Number 379 in 2016.
It was the middle name of President James A. Garfield.
