I have a bowl that belonged to my great-grandmother, who was born in the 1800’s. It is wheat in color and the mark on the bottom is stamped in blue. I think it reads, G.M. & Son at top and definitely reads Liverpool at the bottom. Between the two aforementioned marks, there is a circle surrounded by a design. Inside the circle are the words “ironstone china” that follow the circle.There is a drawing of a pitcher in the middle, between the words ironstone china.

I cannot find anything on G.M. & Son or the mark. Does anyone have a clue about this bowl and value?
