Hi
I cannot tell you the history but the following info from the census might be of interest?
1871 census piece 5294 folio 99 page 44
Does not give a name . Just address No.10 &11 Station Street Chepstow
Robert Griffith head b 1846 Chepstow Mon Beer house keeper
Jane Griffith wife b 1844 Exeter Devon
1881 census piece 5219 folio 62 page 49
Still no name just an address No 10 &11 station street Chepstow
Robert Griffith head b 1846 Chepstow Mon Innkeeper
Jane wife b 1843 Exeter Devon

Sarah wife b 1864 irland
Emily W b 1888 eth Kent
Violet b 1889 East Ham Essex
Eva b 1891 Becton Essex
Kate Cripps b 1888 Chepstow domestic gen servant
I note that in the 1881 census Robert had nephew named Hutchings could the new landlord be a nephew also?
1911 census same family but again does not give Inns name only address as 1871-1891
Wartime Memories of Chepstow mentions The Berkeley Arms
http://www.bbc.co.uk/historyHope this is of some help unable to track down the Inn in 1861 Station Road had not been named, if you look up an old map at the library they may be able to stay what road it was on.
