I think he is my ggg G-father, but need more info to confirm - I suspect the following:
Robenson E -> John R -> Norman H -> John T -> John T -> Me.
He was born around 1832 (although various sources list just his age - such as 1880 Census, age 50 - whereas 1860 Census has year born 1832), married to Unica E.
Here is a breakdown of his family from 1880 Census:
