Dennis Haynes - Ireland to USA

[Haynes]

Hello,

I am searching for any records of when my gg grandfather (Dennis E. Haynes) came to America.  I first find him in the 1850 Lee County, Georgia Census.

At that time he was married to Elizabeth (Betsy) Swearingen and had 3 children; William=4 yrs, Patrict=3 yrs, and Mary=2 years.

The census lists him as being 35 years old, so he would have been born around 1815.

I have been unable to find him on any of the ships to the USA.

Thanks for any help.
