We don't have anything to support or negate the idea of whether a French women could have published in her own name if she was single, or if she was married and addressed herself in a non-customary way.

We just don't and the conversation never went that direction. This is in your interest to understand alone but in a conversation where nobody has provided anything. As such it will be impossible for anyone to prove or disprove your assertions, and may have to be your own area of research, alone.
