JONES William & Martha possible baptisms:
431569 1746 JONES Martha Robert Mary Monmouth
418991 1755 JONES William Robert Mary Monmouth
419245 1759 JONES Robert Robert Mary sweep chimney Monmouth

Does anyone think that it's worth pursuing my next theory? The above might possibly be brothers and a sister who were born in Monmouth and moved to Ruardean with William JONES marrying Susannah HERBERT on 15 Jul 1770 and Martha JONES becoming William HERBERT's second wife in 1796?

Second thoughts - Martha would probably be too old to have had all her children, so I think I have to discount this.

Nevertheless all ideas gratefully received!

I am now looking for a connection between William JONES and Martha JONES...!

If she is also the Martha Jones who married William Herbert in Llantillio in 1796 then:
She could have married in Monmouthshire but was born in Gloucestershire?
She could have been born in Monmouthshire but this did not get noted for the 1841 census?

As William and Martha Herbert of Ruardean don't baptise any children in Ruardean until 8 years after 1796 - do we know if there any additional Herbert baptisms near Llantillio to a William and Martha between 1796 and 1804?

I agree with you that Poole Keynes seems too far away. But it prompted me to search again in a different way and I came up with this possibility which is much closer to home as it were:

Though not relishing looking for 'Jones' in Wales, I'd welcome any help at all, especially if someone has already researched this route!

The Gloucestershire Marriage Index does have a marriage of a William HERBERT of Poole Keynes to Martha HUMPHREYS at Coates 17 May 1797 - but this would seem to far away...

From your replies would it be reasonable to assume that sometime after his first wife Hannah YEMM 1758-1789 died, William HERBERT 1758-1824 and Martha [UNKNOWN now not WOORE] lived in Ruardean Hill and had 5 children:

Elizabeth HERBERT bap 11 Mar 1804 (died before 1808)
Margaret HERBERT bap 9 Feb 1806 married George PARSONS 1804-1875
Elizabeth HERBERT bap 26 Apr 1808 - bur 21 Jan 1880 age 79
William HERBERT bap 26 Feb 1809 - bur 13 Dec 1839 age 30 married Sarah DOBBS
Charles HERBERT bap 6 Dec- bur 15 Dec 1811

If so, I presume that there is no known record for William's second marriage to Martha possibly between 1789 and 1804. Or they may not have married? Is there any way to find out who she was?

According to a note in JL Phillips-Evans article The Herbert Family of Ruardean, when William & Martha's first son William was baptised on 26 Feb 1809 the mother's name was given as 'Ann'. Could this be a clue or a red herring?

As usual, all comments very welcome and any help most appreciated.
