Haven't had a chance to look at the map yet but using the Kildare Observer and the 1911 Census I'm fairly sure Faircross is very close to Littleconnell, which you can find in google maps.
There is a Coffey family living in Faircross in the early 1900s they come up on the Observer in relation to hare coursing there is a Robert, a Richard and a William and on the Census there is a Coffey family with those 3 names living in Littleconnell, also a Mills in the Observer as living in Faircross and the Census as Littleconnell.
Also an ad for land to rent at Faircross which says Faircross is a quater mile outside Newbridge.
