Classic Movie That Involves Memory Loss

I cannot remember who is in it- the actress is brunette. Cannot remember the actor. It’s a black and white film.
I believe the film takes place in England.
A young woman loses her memory (I think there’s something traumatic that happens?) Either she is an artist, or her love interest is? There’s something about painting that is integral to the plot?
And there’s a house that is key to remembering her marriage and her home.
That’s about all I can remember. It is driving me crazy!
