Hi again Angela,
Sorry you couldn't reach the website owner, you could maybe try googling for other contacts in the Littleton area.
If you look at the Irish townland index on
www.thecore.com/seanruadyou can get a list of all the townlands in the Thurles Poor Law Union for instance, which will give you an idea of the place names near Littleton.
The other thing of great use would be a map of the area - the Discovery Series, produced by the Ordnance Survey of Ireland, are brilliant.
As for the census, only two complete censuses are available, the 1901 and the 1911. Both of these could be had on microfilm from your local Family History Library (Latter Day Saints) - if there is one near to you, not knowing where you live or anything!
Another possibility is to contact the Local Studies section of the Thurles Library and enquire about extracts of the census being sent to you (I did this for my own ancestors in south Tipperary, before I realised that the Family History LIbrary near my home could order any microfilm).
William McGarry could well be the name of your great grandfather - but be a bit cautious; the naming pattern seems fairly consistent, but there are variations (my great grandfather's children for example, the first son was named after the mother's father, the second son after the father's father).
Civil registration began in Ireland in 1864, so you should be able to find the marriage cert for Josephine's parents, and hopefully if the ages of bride and groom are correct on the certificate, you might be able to track down the birth certificate for Josephine's father and mother once you know her maiden name from the marriage cert.

Hope this much helps, and let us know if you discover anything exciting!
