Thank you, Annette & Maddie for your replies.
I must admit that I am not 100% sure that I can connect my James Jordan b. 1808 & baptised at Sarratt to a particular Elizabeth Jordan, only by a process of elimination. The other James Jordan born the same year and also baptised at Sarratt, whose parents as you state are John Jordan & Rebecca (nee Kentish) as given on this James baptism record, whereas my James Jordan has only his mother Elizabeth Jordan recorded. Just to confuse matters, the other James Jordan also lived in Chipperfield & ran the buthcher's shop there.
I did think that Elizabeth Jordan b.1790, daughter of Ephraim & Mercy Jordan could have been 'my' James Jordan's mother, but cannot find (so far) any evidence to support this fact. This Elizabeth Jordan had a twin sister Ann and I have not found any further records for either of these two girls, regarding marriage or deaths! They both had two older sisters, Sarah b.1782 & Fanny b. 1786 and an older brother - also Ephraim b.1780 and a younger sister Charlotte b. 1792.
I have researched as many Jordan families as I could find in the Sarratt / Chipperfield / Kings Langley areas to try and link together a of larger Jordan family group without too much luck so far, just several 'isolated' families.
Just to make life difficult, checking at Herts. Records Office, it would appear that no parish records have survived for Kings Langley that cover the period of interest that might have given me a clue or two.
My 3X great grandfather James Jordan b.1808 married first Fanny (Frances Ford) their marriage record does not give details of either of their fathers. When James re-married following the death of Frances, he gave the name of his father as 'Richard Jordan' this I think was to cover his illegitimacy. No trace of this Richard Jordan can be found!
