Edmund,
Thank you very much for your help with this one.
I realise I made a mistake in my original message in that the daughter b. 1829 was Frances Kirby not Dinah - whoops

Strange that Ann was not with her mother Dinah in 1841 even though she would have been just 3 years old. Does 1851 give Dinah's place of birth, this would help me confirm a possible baptism for her?
Thanks again for your help.
