I know it's been a couple years since you posted this and I don't know if you found anything. But there is a book "The Eno and Enos family in America: descendants of James Eno of Windsor, Conn" by Douglas C Richardson the chronicles the Eno family. And yes they do have a Huguenot history. There are at least two other books out there, but out of print. My wife's parents are Eno and descendants of Jacque (John) Eno as far as I can trace. There's another document "The Eno Family From Their Origins in France to the Present" published by the Simsbury Genealogical and Research Library (Vol 17 Issue 2 dated Summer 2010) that also details their past.
