Oh well done joger!
I think the name before 'Dit Verrier' in the margin looks like 'Verigole'
Having now found that, the marriage comes up in the Montreuil transcriptions using that name.
They have the wife as Marie Jeanne Francoise La Fontan,
Her name was actually Marie Jeanne Francoise Retourne. It's a little easier to make out the name of her father Antoine Retourne further down, but the whole entry is so messy with bleed through from the page before, it's difficult to make out.
His parish could be N dame I think.
Goodness only knows why it's transcribed as Lerouye.
It's the same with the two children - Marie Francoise Rose 22.6.1790 at St Firmin. and Francois Stanislas Celestin 20 .1. 1787 St Firmin. Both are given as Leroy, but I have seen the entries, and it definitely says Verrier. Not a Leroy in sight.
It's very odd.
There is a marriage for Laurent Verrier to Marie Anne Cayeux 1734, which must be Francois Louis parents.
Many thanks for finding it - I was sure it must be there somewhere!

Added:
I see you also thought it was Verigole Zefiro.
Good to have that confirmed. Thanks
