I would have read it early 1990s I think.
Set in Britain, starting in 1910s. Woman with 3 (?) daughters, think her husband died. She ends up working in or possibly owning a cafe. I think northern England as they go to Bridlington and Betty’s in Harrogate I think.
She re-marries, husband has a car- this was obvs quite unusual.
One of the daughters thinks she’s very posh and marries Raymond, from a well-to-do family. He dies, possibly from measles, while training to join up in WW1. They have a little boy.
I remember really enjoying the book and read it a few times. I’d quite like to find it again. Can anyone help??
