National Library of Wales
A fantastic free resource for anyone with Welsh ancestors. Not only can you search and view thousands of pre-1858 wills at cat.llgc.org.uk/probate, but you can also access the free Welsh newspapers collection at welshnewspapers.llgc.org.uk. It is also worth looking at their free online collection of journals ( welshjournals.llgc.org.uk/browse) and the Court of Great Sessions of Wales database which can be found at llgc.org.uk/sesiwn_fawr/index_ s.htm.
