Looking for Sarah Hobbs

Sarah Hobbs married William James Hobbs in 1861 at Albury they must have moved to Victoria as I have found 2 Deaths of their children at collingwood, But her surviving son Felix George Hobbs Married Annie Jordan Lawrence in Queensland in 1883 Where Sarah is recorded as Sarah Frances Eccles does anyone know of a marriage between Sarah Frances Hobbs and An Eccles or a death of either. As my gggrandmother looks to have vanished thanks for any help Didee
