Help me identify a lithograph and artist's signature...

[freedom]

i found this old lithograph and can't really figure out the signature.
any help what the artist's name might be? french?
the bottom image is written down low on the litho and the glue and matting material obscured some of the writing: "twilight"?

"port au crépuscule" is "harbor at dusk".

Does appear to be French language.

Unfortunately I am hitting a wall with the artist's name and image searches.

"port au crépuscule" is "harbor at dusk"

thanx, that's more than i had. i thought it was twilight...
also, is the name Larrarin or Lassarin? Larraine? i'm getting stuck on the vertical bumps in the signature. "S" or "R"

[Law]

Last name looks like R. Larroui to me, which is a French or Canadian name

These appear to be by Lorraine but the signature is different. Maybe yours is an earlier piece?
