Hi Richard,
I am not sure who is doing the Ancoats area, if you go to the URL in above there may be a contact page.
I looked up you three names in the Ardwick registers that I did and came across two names they are:
24 Dec 1843 - Julia daugther to Joseph & Isabella Spencer, abode: Ardwick, Trade: Salesman, baptised by: W Bannister Curate, Source: LDS Film 2148094
17 Oct 1819: - Elizabeth daughter to John & Martha Lloyd, abode: Manchester, Trade: Spinner, Baptised by W Wordsworth Curate, Source: LDS Film 2148094
Hope this helps
Emma
