Set in England (I believe)
I remember 2 characters names Bea and Lydia
Bea is a teen
Lydia is a grand mother
The mother has split from her husband and trying to make a better life.
The painter had to hide a painting as he went to war, the family know it’s somewhere but cannot find it for decades.

[Natasha]

Maybe The Garden of Lost and Found by Harriet Evans?
