Joyce Clark "French Riviera"

My mother has a painting by Joyce Clark (24 x 36....27 x 39 with frame) entitled "French Riveira". It consists of trees, an inlet with small boats and a Villa. (I have photos). I have researched her work and I am vaguely familiar with the works of Joyce Clark but all I have ever seen were ocean scenes. Does anyone have information about this particular painting or know how I may research it further. Thank you.
