Right, the name Jonah Phelps is very unusual. There are only 2 such individuals in any post-1837 BMD records in England and Wales. The few census records I can find show that they are father and son.
The younger of these was born c.1831 (census varies 1829-1832) in Gloucestershire, married in West Bromwich, Staffordshire (interestingly where Emma Yarrow seems to have come from), had children born in Worcestersshire, including a son Thomas of approximately the correct age (born c. 1859), and by 1871 had moved up to Barrow in Lancashire, where he died in 1901 (I think, sorry didn't write year down).
Here he is with his family on the 1871 census. On the original census image his occupation is given as Boiler Maker, and there is no further detail of birthplace, just the county:

The only earlier census I could find this Jonah on, with father also Jonah, was the 1841: PHELPS, Jonah M 50 1791 Gloucestershire PHELPS, Frances F 45 1796 Gloucestershire PHELPS, Jane F 13 1828 Gloucestershire PHELPS, Henry M 12 1829 Gloucestershire PHELPS, Jonah M 9 1832 Gloucestershire PHELPS, James M 7 1834 Gloucestershire PHELPS, Fanny F 5 1836 Gloucestershire Piece: 347 Book/Folio: 2 Page: 11 Registration District: Tetbury Union Civil Parish: Beverstone Address: Beverstone County: Gloucestershire
Here is Jonah again in 1881, still involved with metal-working, and son Thomas has left home. Can't be absolutely sure this is your family but a metal-working Jonah and son Thomas seem worth following up a bit more, if anyone can find them in 1861 census. From birthplace of 1861 daughter I think they should still be in Dudley/Worcestershire, but I couldn't find them.
