LANNON Family History

This interesting surname is of Irish origin, and is an Anglicized form of two Irish septs. The surname may have originated from the Gaelic "O'Leannain", descendant of Leannan, a byname meaning "lover, paramour, concubine", or from "O'Lonain", descendant of Lonan, a personal name from a diminutive of "lon", blackbird. Traditionally, Irish family names are taken from the heads of tribes or from some illustrious warrior, and are usually prefixed by "O", grandson, male descendant of, or "M(a)c", son of.

I need help tracing my Lannon back no Ireland. My Great great grandfather, John Lannon, was born in Pittsburg, Pensilvania, US in 1825. I know from Federal US census that both of his parents were born in Ireland ,and that's all I know. I'm looking for Irish Lannons that might have relatives that migrated to the US in the early 1800s . My Lannons were protestants.
