Hi, Contact the Cemetery Office - they will know when and if a burial had taken place.
It is possible - that her name is on the Headstone - but she has not been buried there -
Depends on what family members chose to do - perhaps she lived in a different location at the time of her death - if she is deceased - Perhaps married again ?

There are 30 FAUBERT burials - at the above Cemetery - perhaps some family connected.
