I'm not sure when this was posted but I hope whoever did, will receive notice there is a comment.
My gggrandfather was Edward Foley, born probably 1822-1830. His parents were listed at the parish marriage registry in LaSalle, IL (1857) as John Foley and Ellen Cavanagh. The connection here is Edward emigrated originally to Schuylkill County, PA. He was listed in the 1850 census as a miner. He applied for citizenship in 1854 in PA. He became a citizen in 1860 in LaSalle. We believe he died in 1863 in LaSalle.
Emigrants were known to follow relatives and friends. I've been told Edward was not a common name and I'm hoping your Edward could be a brother or cousin of my John Foley. My assumption has always been John was probably born 1790-1810.
I will spend some time looking through County Laois parish registers looking for connections.
