My family is from Vinnytsya and our original last name was Dechtiar. I fact, my Great Great Grandfather's brother was named Enoch Dechtiar. It would be interesting to know who your Enik was named after, and then who that person was named after.
It have a list of a of about 20 relatives with the last name Dechtiar that were born in Vinnytsya.
I would be happy to share this information with you.
Please let me know how you would like to proceed.
