Elizabeth Suter B1851

Having difficulty in finding out any information on Elizabeth Suter b1851.
Elizabeth was b1851 in East Meon, Hampshire, England. She married Stephen Merritt b1845 also from East Meon on 25th Oct. 1870. Stephens Occupation was a Mariner.
They are mentioned in the 1871 Census as living in East Meon, they had a Daughter Florence Amy Merritt born 27th Oct. 1872.
I have looked in the census's for 1881, 1891, 1901, with no entries for Elizabeth or Stephen, their daughter Florence is mentioned in the census's as staying with her Grandparents in East Meon right upto her marriage to Albert Berry in 1893.
I have also looked into Death's and still found nothing, if anyone has any information or can give me some advice on this query I would be most grateful.

Kind Regards

Richard
