Do you ken Helen?

unnamed, Helen Ken, 9"x12", oil on board

    This was an ebay find from some years ago. I am calling it a plein aire sketch. It is actually quite striking from the proper distance, and well done, IMHO. There is another painting, another sketch, verso, along with an inscription, all of which is fairly clear, except for the name of the town where it was painted in New York. The artist recorded that she painted this work while spending the summer with her "Aunt Lilian". I believe the artist's last name is Ken, but it might be Kent. I have not been able to find an artist by either name. The name of the town appears to be Braincliff, and I wondered if it might actually be "Briarcliff" but can't quite make that fit with the artist's scribble. It is possible that it is "Briarcliff" and was misspelled by the artist.  I found several Helen Kens in searching records on Ancestry.com who are candidates to be this woman, but just don't have enough information to make the identification. Help!
