Meaning of Surname...

Hello,
I am looking to see if Aubin is a Lebabese last name?
My Great-grandmother's name is :
Marie Jose Inoptienne Aubin
Her uncle's name was Elie, and her sister name is Onille
Onille daughter name is Myriam.
I know that they went to Cuba around the 1900s
I am stuck here so if anyone can help, that would br great!
