Hello Ashely
As you can see from my tag a fair lot of my own were Huguenots in London, and I have researched around 60-80 other Huguenot families in London's East End besides, as it is a real interest of my own. Through my own link to the family, the Agombars were one of the earliest I researched, a good 4 years ago, as a contact who helped me starting out was on that line, and she had done a great deal of research. I later checked out and verified it myself as correct.
The later English info comes from a mix of the English parish registers and the transcribed registers of the Huguenot churches made by the Society of GB and Ireland. (The info that Pierre and his parents came in November 1685, relates to them joining the Threadneedle Street Huguenot Church in London at that time, with a paper testimony from their pastor in St Quentin). A few of their family were also inmates of the French Hospital London, and confirm the line back to Broncourt, St Quentin, Picardy, so it is well established and researched.
The earlier French info comes from the existent protestant records for St Quentin. This covers roughly the period from the Edit of Nantes in 1598 which gave Protestants a civil status in France, to the Edit of Fontenbleau, which then revoked it again, in October 1685. This also explains why they fled at exactly that time. Other members of their family are in the Catholic Register, the same month, in their village Brancourt, being forced to 'abjure their heresy' and become nouveaux convertis. Jacob and his wife obviously chose to flee instead of this. Those who stayed, including Jacobs sister, later fled too about 5 years on (perhaps they inititially thought the persecution might blow over). They went to Holland, settling in Haarlem. Jacobs sister and her husband Daniel Le Beau, later moved on again from there, in 1702, to London, with my ancestors the Deverduns. Daniel and Magdelaine were godparents to many of their children here in London.
I've not personally researched the Manchee family but I do know it is also a very well researched family, and I think several decendants of that family have been high up and well involved in the Huguenot Society over past 100 years. If you are researching them too might be well worth getting in contact with them.
