Hi Jean
Thank you so much for your help.
My husband found another message Barbara had posted on an Australian website also in 2001 but we could reply to it and have done.
Barbara has replied to us and has a branch of the LeVert family in the USA.
I have the 1861 census from the Isle of man that you mention and also the second marriage of Charlotte, I also have her first marriage in Paris to Joseph LeVert.
I dont know why they were on the Isle of Mann and they only appear for a short period.
Sarah Webb is their maternal grandmother whose second marriage also took place in Paris, Maybe Mr Webb was from the Isle of Mann.
Thank you once again for your help
Catherine
