Thank you Bernard, for creating d'Estienne d'Orves's profile.
Concerning the LNAB, you are right that the conventions are less tight for recent profiles than early ones. If I play the purist, I would say use "Estienne" because that is the basic name of the family. Now the d'Orves branch started in the 16th century, which is a long time ago, and in this case "Estienne d'Orves" should be preferred. Honestly, I would leave the name as it is. Take a lot of time to think it over. It might turn out that "d'Estienne d'Orves" is the best option for him in the end. If you are to change this name, remember that it should not be changed more than once, twice maximum, because of redirection problems. I had/have this dilemma with a number of profiles, and even 2 years later, I never know if I made the right choice.
About connexions... Well, I cheat. I go to Geneanet and hunt for some contributors I know to be specialized in them. Then I see what they have. Then I follow their path, but with sources (which Geneanet connectors usually don't have). Sometimes it turns out they are wrong, or some individuals along the path can't be sources according to WikiTree standards, so the connection path doesn't work. I'll take a look at Honoré to see if there are any familiar names there. Having lived in the town next to his birth town for ten years, I should take special care of him.
