Nikita: if the information that he had been married 13 years in 1911 is accurate, and he was living with his family in Derby, then I think I'd take a punt on the following marriage which surely merits further investigation:
George Henry Holland married Mary Ann King or Gertrude Helen Taylor: Registered Derbyshire, Belper 1897 Q1 volume 7B page 750
We can rule out Gertrude Helen Taylor because:
George Henry Holland married Mary Ann King in Ironville in 1897: Derbyshire Registrars Marriage Index ICC/02/044, Register Office 392
