My name is Ariel Birdoff. I can trace the Birdoff family back to "Russia" in the 1800's with Benjamin Birdoff. I was told that perhaps our name was changed to Birdoff because we actually came from Berdichev in Zhytomyrska. It's also been suggested that our surname could have been Berdichevsky or Berdichevskya or something of the sort. If anyone knows of someone who would know more of where the name Birdoff came from or know of anyone who had a son named Benjamin, that would be VERY helpful!
