I have today updated my Evans genealogy online, to include information about Robert Evans bapt. 1785.
My Cousins in Niagara, Canada - Elizabeth and Sherry, kindly supplied this information to me.
As can be seen, Robert served with the British 82nd Regiment, 1st Battalion from 1808 until 1815. He fought at Lundy's Lane, Niagara, Canada in 1814.
It is in the Niagara area that he settled and his descendants now live.
