After the death of David Collot, she married Amaury de Mardeaux, who died before 1666, i.e., before she did.

According to [BHSP]308, she hated the children of her first marriage, and burnt all the documents and proof of nobility, so that they couldn’t inherit the property of their father. In my awful translation:
“After the death of my grandfather, my grandmother married again to a Demardaux, a papist, with whom she had children that she loved much more than those from her first marriage, one of the only things it is not possible to criticise[?]. She was a strong-minded woman, with a great deal of merit, but her hate for the children of her first marriage, as well as my father, was so great, that after having taken all their property and goods and given it to her husband and his children, she burnt all the titles and papers of her late husband, to prevent his childen getting their hands on his property. As proof of this, it's what she said to me herself, having been to see her one day while passing through Vitré, when I was around 14 or 15. ``Ah", she said to me, caressing me, ``if I had known I was going to have such a pretty grandson as you, I would never have done you such a great wrong as I did, and I would have taken greater care to preserve your titles and papers, from which you could see who you are [?], until such time as you could have inherited the property of your grandfather."

This Demardaux was just as zealous as their mother in persecuting the children of his wife's first marriage, to make them change their religion, and he succeeded in converting my uncle Philipe and my aunt Margerite. But for my father, God delivered him from such misfortune, although for two years after the death of his father he was at the mercy of his unloving mother and stepfather. As his temperament was strong, even a little violent, full of honour, courage and heart, be began to resist the abuse of his stepfather, and would never rest until he was free of it [?]. This is why he consented easily to my father's proposition, to equip him and send him out to seek his fortune with Monsieur le Marquis d'Antrague, whom he remembered as a very good friend of his father.”

Ec. sgr. d’Escury and de Landauran near Vitré in Brittany.18 Married, firstly, 1n 1583, Dlle. Philippe de Villorio, who died childless in 1601. By this marriage did the seigneury de Landauran come into the Collot family.

Originally from Picardy, near Noyon.308

[BHSP] says:
“Before I talk about David Collot, esquire, seigneur d'Escury, my grandfather, let me say first that it is now impossible to learn more about his ancestors, because his second wife, hating the children of her first marriage, burnt the papers and the titles of the family of my grandfather, as we shall see in the following.

But David Collot, esquire, seigneur d'Escury, was originally from Picardy, near Noyon, as I have read many times in his marriage contract with Françoise-Philipe de La Villorio, a family of note in Brittany, whom he married in 1583, and with whom he had no children [this doesn't make sense. If she didn't have children who were her heirs? I need to get better at tranlating French]: she died in 1601, and although she left him everything in her will, as he was already well off, he gave to the heirs of his wife everything she had left to him.

The said David remarried in 1606, to Marie Le Noir, whose mother was a Coisnon. They had three children, to wit: Philiphe, André and Margerite: he lived with her only until 1612 when he died, leaving his three children, of whom the oldest was only 4 and a half years old. My father, called André, was only two years old, being born in May, 1610.

They were given tutors in 1613, Messieur de Beauchans et Messieur Le Noir, their mother's brother. Neither these gentlemen nor the mother profited from the children. [I don't understand the next bit. Something about the tutors wanting to get their hands on the money, but couldn't. The children were told to do everything they were told because they had nobody to protect their interests.].

Everything that we have been able to learn about the origins of her husband, was told to my grandmother, Marie Le Noir, by her late husband David Collot, esquire, seigneur d'Escury. He said to her that when he was about 15 years old, and his brother a year younger, his mother was killed in the massacre in the church at Vassy, a small town in Champagne, on the Bloise, in the first religious civil war in the reign of Charles IX. His mother perished in the church at the hands of the army of the duc de Guise. While they were chanting Psalm 88, the barbarians entered the church, sword in hand, and massacred everybody there, and he and his brother could hear their mother, who was a widow, asking God many times to save her children, for the sake of her who was dying for his holy name [?. Not too sure about this translation].

David Collot and his brother, having been noticed by the troops to have white on their hats, as the troops had put on theirs, were thus saved. David went to the Bishop of Noyon, a good friend of the family, where he hid for three days, after which time the Bishop said he had to leave, as if anybody discovered that he had given asylum to David, he himself would be killed. So my grandfather went to Brittany, to the house of Monsieur le comte de Fretigny, who took him in very willingly and looked after him until his marriage to Françoise-Philipe de La Villorio.

At this time, Henry IV took the throne of France. My grandfather took the opportunity to go to Vitré, a small town of the Messieurs de la Trimouilles, in Brittany, where there was a large church maintained by those seigneurs [presumably a Protestant church]. There, finally, he was able to gain the consolation of his proper faith, in a way that had been very difficult to do previously.”
