Thank you Rosie, Carole & Sandra for that information, especially the newspaper reports.
Yes they are that couple who moved to Hoosick Falls, New York for the 1880 US census & prior to that were in Orange, NY for the 1875 NY census. After Armanella died in March 1892 Benjamin returned to England and married Mary Anne (Marian) Speller in Soham, Cambs on 25 May 1894 where he is recorded as being publisher & editor of the 'Rensslaer County Standard' of Hoosick Falls, NY. After their marriage the couple returned to New York.
They are found on 1900 US census in New York but seem to have returned to England in Sept 1901 initially to Soham but moved to Lowestoft, Suffolk around 1903.
