Ashe,
To answer your PM request for more information, and so that other Rootschatters can continue to follow the thread, here’s what I found……
Simon CORNEJO aged 31 married Margaret MACGLINN aged 26 on 25th September 1858 at St Mary Church, Kooringa.
Fathers = Jose CORNEJO & John MACGLINN
Ref = Bur 35/5
So yet another spelling of the name.
Here’s the death of their baby son Henry that I missed…..
Henry White CORNEGO aged 3 days of Worlds End died on 5th February 1866 at Worlds End.
Father = Simon CORNEGO
Ref = Bur 22/351
The death of Mary Jane CORNIGO who married Robert RAMAGE……
She died aged 84 as a resident of Parkside on 7th May 1946 at Parkside.
Husband Robert listed as deceased.
Ref = Ade 700/2149
Robert died 15 years earlier.
He was aged 68 and resident of Dulwich when he died on 24th July 1931 at Dulwich.

Hope that helps.
