Can anyone tell me what type of familial relationships would have
required official permission to marry in France in 1901?

First cousins, uncle and niece, aunt and nephew. As far as I know, it is
still the case.

== Sorry, my first answer was too quick.
Ther is no more permission needed for first cousins, but it is possible to ask for a
permission if you want to marry with your adopted sister or brother or with your
son-in-law or daughter-in-law, or with your step mother....

I'm not able to answer your question and I guess that many other
people will do it. But concerning some memory work that I was doing
recently, I met the story of a man (born 1903) who married a French
woman without telling her that he was already married abroad... Of
course, it happended during WWII, but still... Nowadays, it would be
much more difficult, although...

I just know that nowadays, a niece (or a nephew) can't marry her
uncle (or his aunt), but he can ask for an official permission >from
the Preident de la Republique himself.

On the other hand, the marriage is allowed without any proble between
first cousins (I know several of them).

My great-great aunt married a relation in Lyon n 1901.
They were close enough relatives that they needed to get official
permission to marry.
He had just been widowed and was left with 4 children and needed to
marry someone ASAP to help out with the children and my great-great
Aunt was willing so they were granted permission.
