Have you tried ordering the marriage registration of Job Challoner? There is a marriage from the 4th quarter of 1854 in Great Boughton that has a Job Challoner and Jane Evans on the same page (vol 8a, p 479). The registration should have Job's father's name listed.
Job and Jane are in Cheshire on the 1861 census with son John (6) and daughter Emma Jane (2 months) in Chester St Oswald, Cheshire (Piece: 2631; Folio: 68; Page: 23). In the Free BMD there is a birth for Emma Jane Chaloner that was registered in the 1st quarter of 1861 in Great Boughton, Cheshire/Flintshire (vol 8a, p 346). There is only one other Emma Chaloner listed being born 1861 (+/- 1 year) and her birth was registered in the 2nd quarter of 1861 in Wrexham, Cheshire/Denbighshire/Flintshire (vol 11b, p 327). The birth registration will say who her parents are.
The family is in St John The Baptist, Cheshire on the 1871 census listed as lodgers in the household of Sarah Hughes. The family consists of Job Chaloner (49, carter, born Holt), Jane (39, born Holt), John (16, clerk solicitors general, born Holt), Emma J. (10, born Chester) and James C. (3, born Chester) (Piece: 3723; Folio: 33; Page: 8 ).
