Ethelinda was born in Hawaii to an artistic family. Her mother, also an artist, studied with Nicolai Fechin and influenced Ethelinda's love of painting. Ethelinda says, "I have always painted, first sketching the characters of the books my grandmother read to me as a child."
Ethelinda studied art and English literature in college and went on to learn French in Switzerland. She traveled extensively, spending time in New York before settling in New Mexico. Ethelinda says, "Perhaps this is why my artwork is so diverse. I paint what is around me - right now, in New Mexico, it is horses. The most important aspect to me is to see subject matter and paint them in a manner in which they are not painted elsewhere."
Charlotte Berny in Focus/Santa Fe writes, "Ethelinda's vision transforms her subjects. She begins with things that are real - horses, Indians, fruits, flower - and then through some alchemy, recreates them as grander versions of themselves."
Ethelinda's work is shown at the Booth Museum in Atlanta, Georgia and the Nelson Museum in Cheyenne, Wyoming.
