When you think about looking into the history of World War One - you'd probably think a library, or even a memorial would be a good place to start off.
Well you might not even have to open your front door - because there's a new campaign calling for people to go through their family papers and see if any of their relatives took part.
It's called 'Never Forget Your Welsh Heroes'and organisers want as many people as possible to get involved. Megan Boot reports:
The Heritage Lottery Lottery Fund (HLF) has awarded a grant to help Brecon remember the First World War. The grant has been given to the 'Brecon Remembers' project and will enable people to research the stories and backgrounds of the names on local First World War memorials.
The announcement of the grant award marks a year to the day that the First World War Centenary commemorations begin on 4 August 2014.
A Welsh village that didn't lose a single soldier in World War One has held a ceremony recognising their contribution to the war effort.
Colwinston in the Vale of Glamorgan is one of three villages in Wales and 51 across the UK whose soldiers all returned home.
They are taking part in the 'Thankful Villages Run' - a nine-day charity ride around the communities.
Three villages in Wales are among 51 hamlets in the UK taking part in a charity event to recognise the contribution made by returning First World War soldiers.
The 'Thankful Villages Run' is a nine-day charity ride, which started in Llanfihangel y Creuddyn - near Aberystwyth - this morning and will run for eight days.
The journey will stop off at 51 communities and present them with a slate plaque to commemorate those who were fortunate enough to return home at the end of WWI in 1918.
Llanfihangel y Creuddyn in Ceredigion, Herbrandston in Pembrokeshire and Colwinston in Glamorgan will all get plaques.
The ride will raise funds for The British Legion.
