Child of Cj Sutton Manning OR Kemp Born 1892 Pos Melbourne

I am researching the names SUTTON and MANNING (originaly from Wicklow Ireland). Both names appear in an index of missing people as follows: Sutton CJ,farmer, Catling, NZ wrote in 1895 for details of wife's child born 1892, Melbourne.
She left him 1891, pregnant by man named KEMP. She used the name Manning. She had brother in Brunswick.
8 pages List 29.
Could anyone provide additional info please? Many thanks,
Kind regards
