I'm leaning towards Suzanne's surname being written Jaullin, as the upper part of the first letter doesn't have the characteristic anticlockwise loop of 'S', which can just about be seen in 'Suzanne'.
This writer seems quite inconsistent in his use and style of upper case letters: this entry begins with Daniel fils de Daniel bruneteau, and the next one Daniel fils de daniel Delouche - and in both of them, the 'D' of the child's name is different from the 'D' further along.
