Edwin Harris Keech - Incorrect marriage (Hume)?

In a short time of looking, I haven't found any proof of Edwin marrying Eliza Hume (or Keech).

I did find some compelling a record for a marriage to a Lillie M Moore
12160/1916
KEECH
EDWIN H
MOORE
LILLIE M
TAMWORTH

Alongside his marriage to Charlotte:
4026/1880
KEECH
EDWIN
MOGG
CHARLOTTE HENRIETTA
MUDGEE

For what its worth, a record of Eliza Hume marrying Ernest Keech also exists:
4705/1900
KEECH
ERNEST L R
HUME
ELIZA F
ST PETERS

And a birth record for Mabel
KEECH
MABEL B

ERNEST L
ELIZA F
