I wonder if this (click) means we've found the songwriter names:

EATON W.G & HUNTER HARRY.: "Jonathan. Joseph. Jeremiah" Or "Named After Everybody."
London, Francis Bros & Day.1877-81. With an unsigned colour lithograph portrait, of the singer/publisher/Minstrel James Francis of the Mohawk Minstrels. The lithographic artist has drawn a small dinner suited body and added a colour photograph of the head of James Francis. We can date this certainly between 1877 when Francis Bros & Day started and 1881 when Harry Hunter was persuaded to join them both in the Mohawks and in the publishing business. It is likely to be 1881 as the back cover confirms the arrival of Hunter into the partnership with a list of songs. William G. Eaton has 13 titles to his credit in Kilgarriff, many of them music hall songs.Folio size with music
