Re. Gwen's family.
Some said that she comes from a wealthy family with UK attaches (a Mouchel funded a successful company in UK in late 19e century).
After researching, it appears that this funder (Louis Mouchel) never married and died childless.
Mouchel is a common name in the North of France : especially in Cherbourg area where Gwen's family comes from.
There's no evidence so far that she's from this wealthy family.
I'll keep doing my Investigations
Re. Sadie's latest video in the "dark side" of Paris.
She missed the point with the tents in the streets.
They're more likely for illegal migrants who are trying to enter illegally UK via Dunkerque/Cherbourg/Calais.
These tents are given to them by associations who help them.
Maybe some are used by homeless people but not all of them.
These migrants are regularly arrested by the French police and deported but always come back to same point : Paris before heading to the North of France and then, trying to smuggle in trucks or small boats to England.
