All I searched on was butterfly butter dish; I didn't use Sowerby
Connotations springs to mind

. Obviously yours provided results! If you see from my heading and initial information, I did not search via. "butterfly butter dish". I was unaware it was a butterfly dish or a "butter dish". In fact I did look under trinkets also. I was not even sure, that the lid was part of the bowl as they are in two different styles. I suppose I should have also incorporated that into my initial enquiry. So again, I really do thank you for the link. Your always there when needed.
