I found a first hand reference to her in the writing of her brother's wife, Charlotte d'Arbaleste: [1562] [Philippe de Mornay’s] illness lasted nearly three months and during it his mother was obliged to leave her house, on account of the troubles, and to take refuge with Mile, de Montagny, her maternal aunt, who lived a league away from Buhy. She had with her the six children still left to her, four of whom were ill, and her two nephews, M. du Bourry's sons. She took them all, Philippe and Anne de Mornay accompanying her in her own coach as they were the most ill. The whole family stayed at Montagny till the troubles were over and during the whole of the time all her children and both her nephews were ill. http://archive.org/stream/huguenotfamilyin00mornuoft/huguenotfamily...
I think that's enough to validate her existence.
The Racine history pages are excellent - I'll add them as Resources to the duPLessis project too.
