This is the Alfred and Eliza that Bertha "Haynes" is living with in 1911 (no sign of daughter Eily with the family in 1911).
The birth of Eily in Abergavenny links with the Abergavenny marriage of Alfred Haynes and Eliza Davis - but cannot find a birth on BMD for Eily in Abergavenny around that period.
The marriage year of 1897 accords with Alfred's declaration on the 1911 Census of having been "married 13 years".
