SOLVED. Family saga: poor fish gutter becomes millionaire by selling fried fish after cutting hand

[Shellistar]

I read this book in the 90’s but it may have been written earlier.

Set in the late 19th century I think, a man working as a fish gutter cuts his hand on a knife when working and can no longer work to support the family. He instead sells trays of fried fish, increasing business, eventually becoming a millionaire. One of his sons isnt very nice so in the will is left the original knife that started the journey.

Might be Hardacre. I read it so long ago I can't remember if he cuts his hand, but he starts out as a fish gutter.

OMG THIS IS IT!

Thank you so much. I remember it had “acre” somewhere in the title. You’re amazing x
