I have the following French/Jersey surnames in my ancestry:
JEHAN
GALLIENNE
GOSSELIN
LE BRETON
LE BROCQ
LE MARQUAND
LOZUET
RABET
Therefore, I have to do a lot of research amongst French records and websites. I have subscribed to a great website called The French Genealogy Blog.
I can’t recommend it highly enough for it’s value and substantive knowledge about researching your French ancestry. One of the posts focuses on French surnames and all the books and resources out there that may help you with your research.
A website they suggest that might be of great use to you is: www.geopatronyme.com.
Good luck with your research!
My Channel Island Ancestry 
Interesting site, the Lazarevic famiy all came from one area in Montenegro. They also use the name Luke within the name. Thanks for the french links. Majority of the old lineages have slav or sav in the name the name below doesnt list it Still maybe related.? I know of two males related one my great grandfather Vukosav Luke the other was Oglivana Wright’s father my cousin she grew up with the royals overseas.
