Palette style Haitian(?) painting - signed Henry M Gustave

I found this at the local thrift store today. I like haitian paintings and I like palette style paintings - so I really liked this when I saw it!
But the signature doesn't look Haitian; it looks like it says Henry M Gustave but I've never heard of a Haitian artist named Gustave.
Googling the name I found a lot by a Gustave Henry Mosler - is that my guy?
Does anyone know who the artist is of this painting?
Thank you!

 

I can't believe he didn't come up for me! I got Bing with my acer but it's honestly one of the worse search engines - I usually go to Google and then look for what I'm searching for but I really didn't think there was a Haitian Gustave so I didn't.
Thanks I need help!
When I go to google it sometimes asks if I want to make Google my main search engine on my laptop - I think I'm going to try to do it!
