"Hi, I have spoken with Kevin recently and am headed to London in May so might catch up with some family who are also related and see what they have. I am trying to get some of their info relating to addresses the families resided in post France, ie The Netherlands and then in London. Are you local to Queensland?"
No, I'm in Sydney. I'm off to France myself in April and hoping to visit Meaux en Brie near Paris where Judith Bachelier came from and also going to the West to Mouchamps in Vendee where the Cordons came from (Marie Bentley, daughter of Judith Deverdun, brother of your Timothee Deverdun, married Francis Cordon). Re London addresses, I have Anthoine Deverdun living in Silver St, Stepney at the time of his daughter, Susanne's baptism in 1709.
