You probably are aware that as Wales was administered as part of the same political entity as England for a long time, many online resources are the same as those for England - example Welsh Civil Registration also began in 1837 and their indexes for births, marriages and deaths can be found in the same places as those for England.
But of course there are others
The UKBMD site has many Counties listed, while there is also a general list specifically for North Wales.
The Wales Genweb site has many email lists, archives, Query Boards and links, also some specific county guides.
The GENUKI site is similar to the one we already know for England and holds a lot of detail together with examples from the 1868 National Gazetteer and links for the history and location of Welsh church records.
Useful Maps of Welsh Countiesin 1833.
A new site for the Association of Family History Societies of Wales and some individual counties have their own sites such as Clwyd with a wonderful set of church photographs and Dyfed FHS also has links for Cardiganshire, Carmarthenshire and Pembrokeshire.
There is a huge collection of links to Welsh resources on the Relative Linkssite.
Don't forget the Historical Directoriessite and also Ancestrywhich has directories from Glamorgan and Monmouthshire and all Wales guides in it's UK and City County Directories 1600-1900 Collection and The Genealogist has Pigots Directories for North and South Wales.
The OGRE Projecthas the digitised images of the 1873 Landowners' Returns for Wales for free, broken down into individual counties. The Genealogist and Family Relatives have these searchable, but not for free.
Right up to date is the completion of the 1911 Census Returnsfor Wales. Findmypast have a language help sectionavailable including a basic translation table.
It's worth searching newspapers such as [urlhttp://archive.timesonline.co.uk/tol/archive/] Times[/url] or the Guardian.
The National Library of Wales has a lot of digitised material including an index to the gaol records of the Court of Great Sessions from 1730 to 1830, early applications for marriage bonds, a register of Welsh manorial documents and wills proven in the Welsh Ecclesiastical Courts pre 1858, although the highest probate court for wills was the Prerogative Court of Canterbury whose records are held at the National Archives and more databases for Glamorgan and Flintshire will be found on Ancestry's site.
The locations of records held in archives throughout the country can be searched for in a number of sites such as Archives Wales, Access to Archives and the National Register of Archives
Gathering the Jewels is a website for Welsh heritage and culture and for details of many Welsh museums visit National Museum of Wales
Last but not least is a great site for dipping into for facts, figures, tales and mysteries - Data Wales
