Meath is the 2nd largest county in Ireland and is mainly farmland of very high quality. Dublin has encroached on its borders which are now more populated. It is home to Newgrange a passage tomb more than 5000 years old and the oldest place in the world based on time, in the winter solstice the rising sun travels up the passage to light the burial chamber. If you google Newgrange and also Dowth and Knowth you will see what I mean.
The famous Battle of the Boyne occurred in Meath in 1690 near Drogheda. King James II (Catholic) of England was defeated by William of Orange (Protestant) to take the english throne and eventually led to the division in the country.
While much later than your ancestors you can see census for 1901 and 1911 on http://www.census.nationalarchives.ie/http://www.census.nationalarchives.ie/ and may still see your people there. I see in the Surnames of Ireland that the Gorman name is from County Clare but it is around the place. Also Fay is a name from a Norman family that settled in Westmeath in the 12th century.
