Crumbs this case just gets more and more of a puzzle doesn’t it.
I couldn’t find Lilian Nesbit Charles Clark either, who were these people and a gold mining company?
Perhaps this man travelled abroad.
Kind of fearing this wasn’t the right birth either and yet there is the link with Kings Road address.
However that would make him only about 19 when he married not 27.
Re the sister info it was crossed out wasn’t it so I wondered if it was just written on the wrong record?
Otherwise yes it could conceivably be the woman he was having an entanglement with, anything is possible with this case!
