Incidentally, that marriage is in the IGI (with the names of both fathers).
Also what is very likely to be Ann's christening:
Ann TUNNALY bap 10 Aug 1834, Saint Alkmund Derby Derby, parents Samuel TUNNALY and Patience.
And the following other children to the same parents, same parish:
Thomas TUNNALLY bap 28 Feb 1836
Sarah TUNALEY bap 7 Oct 1838, died 21 Feb 1840
Jane TUNALEY bap 5 Apr 1840
The above are all extracted entries. There is also an LDS submission for the marriage of the parents:
Samuel TUNALEY m Patience PAGE 27 May 1833.
And possibly Samuel's christening (extracted entries):
Samuel TUNALEY bap 24 Oct 1810 All Saints Derby Derby, parents Thomas TUNALEY and Elizabeth
Etc.
Pigot's Directory of Derbyshire 1835 at:
http://www.genuki.org.uk/big/eng/DBY/Pigot1835/dbyderby.htmlincludes under DYERS a Thomas TUNALEY of Tenant St and a Thomas TUNALEY jr of Derwent St.
