struggling with Sarah BEVAN wife of John BEVAN (General)

by macast , North Yorkshire, England, Saturday, October 18, 2014, 16:44 (3690 days ago)

I wonder if someone can help me sort something out.

I have John BEVAN (a son of William BEVAN) born 1843 who married Sarah MORGAN of Thornbury, Gloucestershire in June Q of 1864 in Gloucester, England.

then I have John BEVAN (a son of William BEVAN) born 1843 who married Sarah TERRITT born Ruspidge, Gloucester at Flaxley 14th Sept 1874
(witnesses were James BEVAN and Emily BEVAN.... two of John's siblings names)

in the 1871 census we have
John BEVAN
Sarah his wife
Albert son abt 1869
Virginia daughter abt 1870
Arthur son abt 1871

then in the 1881 census
33 Woodside Rd Cinderford
John BEVAN abt 1844 Cinderford (East Dean), Gloucestershire, England Head Flaxley, Gloucestershire
Sarah Bevan abt 1847 Ruspidge, Gloucestershire, England Wife Flaxley, Gloucestershire
Albert Bevan abt 1869 Ruspidge, Gloucestershire, England Son Flaxley, Gloucestershire
Prudence V. Bevan abt 1873 Cinderford, Gloucestershire, England Daughter Flaxley, Gloucestershire
Sarah A. Bevan abt 1875 Cinderford, Gloucestershire, England Daughter Flaxley, Gloucestershire
Ernest F. Bevan abt 1877 Cinderford, Gloucestershire, England Son Flaxley, Gloucestershire
Agnes Bevan abt 1879 Cinderford, Gloucestershire, England Daughter Flaxley, Gloucestershire
Arthur J. Bevan Cinderford, Gloucestershire, England Son Flaxley, Gloucestershire

can someone help me and take a look at the actual records and work out what is happening.

did the first Sarah die and then John married the second Sarah?

or are these two different families that I have got mixed up? (although they have used the same children's names).... Virginia 1879 and Arthur 1871 have disappeared and been replaced by younger Virginia and Arthur

any help would be appreciated..... thanks
