Help with look up for 9th G Grandmother from Tarn France

[tornado]

Hi everyone. I thought the time to stop Family research had been and gone , but no. I was wondering if anyone familiar with French records could help me with a look up?. My 9th  G Grandmother was a Marie d' Amalvy born 1625 in Tarn France . I know this is a long way back but i am still curious and Marie is still worthy of research i think. If possible i would like to know about her lineage . I know her Husband was Pierre de Bonafous . Also , "Was the Bonafous Family a renouned one in Tarn?". Some Families have interesting stories . I appreciate any support thanks.
