I have today translated this from Louis Rossier's 19th century work the Protestants of Picardy which I cited in an earlier post:
"At Oisemont , Paul George, brother of Samuel, was replaced [as pastor] in 1665 by Pierre Bories, as was he in 1667 by Jacques De Vaux, the former pastor of that same Temple.
The Order of the Lieutenant-General, Thierry, to gather evidence against De Vaux and Phillipe Bernapré, was made at the request of the Kings Prosecutor on June 10, 1671.
According to testimonies, given at different times, in front of the Provost of Vimeau, the services there were held in the upper room of Oisemont Castle. 50 people were admitted, the surplus had to wait in the courtyard, then they would be admitted for a second service, and a third was held in the afternoon. A butcher called as a witness, however, asserted the assemblies sometimes held up to 90.
This was still far from the figure, of approximately 500, which the Bishop later claimed the meetings were attracting at that time. People came there from the towns of Oisemont, of Senarpont and of Hornoy, the villages of Heucourt, of Croquoison, of Vergies, of Vraignes and other surrounding places.
Interrogated once already in July 1671, by the Lieutenant-General himself, De Vaux, De Bernapré, and his son John, were interrogated once again in the November of the same year. They were questioned as to the residence of Bernapré's father, to the number of religious services held, to the number the persons who attended it, to the salary of the pastor.
Among the allegations 'under investigation' were a funeral allegedly held before nightfall, and a wedding announcement published in the assembly during worship, all things contrary to the judgement of the Royal Council.
De Vaux had to submit his records to the authorities, and it is probably due to these circumstances, that we owe the preservation of the one surviving register of this congregation(1):
(1)The register, conserved in the National Archives date from April 1667 to October 1671.
They contain records of 16 marriages and 76 baptism. The names which occur most frequently are : Le Roy, Nourtier, Le Clerc, De Visme, De Bettembos, Desmaret, Delassus, Gambier, du Hamel, Vauquet, De Moufflier.
Also to be found are Charles Routier, De Bernapré and his son, De Rambures of Haudecœurt, Jean de Rambures (spouse of Blanche de Rambures) of Haudecœurt , Philippe de Rambures of Huileux.
The register is certified by De Vaux, the minister, De Bernapré and De Moufflier, elders of the Oisemont Temple, and given legal status by De Bacq, civil officer, for the baillage of Amiens."
As well as the confirmation of the link between the De Bettembos family and this temple, it also confirms the congregation was being put under pressure at the time the family left for England 1671-74. It's quite possible the temple was in fact closed as a result of the above investigation as it was (at least allegedly) in contravention of the very limited conditions Protestants had been allowed for their freedom of worship by the Edit of Nantes in 1598. In fact before the total revocation of the Edit in 1685, something like 80% of France's Protestant temples had already been closed down or demolished, by the above means.
