Hi Alyson,
Since I posted I have picked up more information.
George Rossiter was born circa 1815 in East Coker. He married Elizabeth Bishop at Wincanton in 1840. When she died in 1842 he married Mary Jane Newman at Ringwood in 1849. They had about 10 children born either at Ringwood or Fordingbridge.Ann was one of those children. George died in Fordingbridge in about 1897.
Ann married John Hext but I don't know where...probably at Fordingbridge. As far as I know they had 5 children. If you have any info about them please let me know.
Hope this helps.
Best wishes
Kevin
