My grandmother's brother, Joseph Smith, married Vilo Lilian Playford in 1900.
Vilo is an unusual name and prone to mistranscription, giving these first name Censuswhacks :-
1891 Searching with 'Vils'
1901 (PRO) Searching with 'Vils Sm*' (search engine won't allow forename only search)
1901 (Ancestry) finds three ladies called Vilo, but only one Vilo Smith
