I think your Folans may be related to mine. I can't prove it because the names of the parents of James Folan and Bridget Joyce were not recorded on the church marriage record of 12 Feb 1892 in Spiddal. But based on the childrens' names, I think James was the son of James Folan and Julia Folan (nee Folan) which would make him my great-great uncle. His sister Ellen Folan Feeney was my gr-grandmother. They had a brother Thomas in Norwood, Massachusetts and the Folans were originally from Cor na Ron, Inverin, County Galway.
Your Folans are in the 1911 Ireland census, in Selerna, Loughanbeg which is online at http://www.census.nationalarchives.ie/search/
Would love to share info!
