I am sure...in the process of a one name study for the Farleys on Wikitree. Have not identified too many from Ireland but here is the link: http://www.wikitree.com/wiki/Category:Ireland_Farleys
The name study is not "done" and never will be, but this may be a start for you.
If you would "log in" or join WikiTree (it's free!) then I can probably be of more assistance if you set up the info/tree with what you do have already. It's very difficult to track a Farley in any country or time period without a little more to go on.
