Bigamous Marriage of William Augustus Catt 19th November 1916 to Unknown Female He May Have Had an Assumed Name Possibly IN Liverpool

I am looking for a bigamous marriage record for William Augustus Catt, born 1886 and legitimately married to Adelaide Harriet Hawke in Camberwell in 1906. According to a newspaper cutting of his trial, the bigamous marriage took place on 19th November of 1916. I'm not exactly sure where they married, but it was likely to be Liverpool as this is where they met and where he is later convicted of bigamy and sentenced to 6 months (I have the newspaper cutting confirm this. In 1911 census he is living away from my G-Grandmother and his family in Toxteth.)
