Unknown Painting with Girl sitting in a Field 16x20

Pretty painting I’ve had for few years showing a girl sitting in a field of flowers under a blue sky. It measures 16x20 out of its frame. It is signed but I’m unable to read the signature. I think the first letter of the last name might start with a Z but I can be wrong. I’ve had great success identifying items with the help of collectors weekly so I figured I’ll try again. Thanks for looking.
