Have you looked at Brian Lawson's burial index? Unnamed children were included at the beginning of each set of surnames, e.g.
KELLY, d/o Robert infant Mar 25 Nov 1846
KELLY, d/o Robert infant Lon ** Feb 1847
KELLY, i/o John 0 Rus 12 Feb 1849
KELLY, ... 4 dys San 3 Jul 1907
KELLY, Infant 10 min Dbc 12 Jun 1947
KELLY, ... Dbc 10 Feb 1966

If they were named they should be on his list.
