"Their first child was born at 11:30 a.m. on Friday, March 14, 1879, in Ulm, which had recently joined, along with the rest of Swabia, the new German Reich. Initially, Pauline and Hermann had planned to name the boy Abraham, after his paternal grandfather. But they came to feel, he later said, that the name sounded "too Jewish." So they kept the initial A and named him Albert Einstein."
The above is from page 11 of "EINSTEIN" by Walter Isaacson.
I just started reading this book today.
