The St Bartholomew Day massacre was in 1572...Aug 24...
Some of my Huguenot ancestors ...another line... fled into Holland after that...
Unless you mean after the Edict of Nantes was revoked in 1685...
I kept falling asleep during that part of the history class .. too much beer the night before ... so I’m a bit rusty on that period ... suffice to say your ancestors missed the horror.
