Help with signature written in pen on a painting?

I found this today at a thrift store; it's the first decent painting in a week at least so I got it (some of us regulars were talking while waiting for door to open & consensus was it's been slow because everyone has been buying school supplies & clothes for their kids and with the prices today they were not in a donating mood afterwards!).
The signature is in pen & I can't figure it out - can any help?
Thank you!

 

Don't think it helps much, but ...

 

I see a quetzal so I'd start with Guatemala.

Looks like the first one has a GL as in Gloria or CL as in Clement. The last name looks like it starts with Cat or Caj. I wonder if that line that sinks low in second wasn't a type of overemphasis or even mistake, or just a way of writing something that no one else does.
