The site was cleared shortly afterwards because the council acquired most of the property between the bank and the bridge, for redevelopment to create Corporation Street c1913-14. Rotherham Archives has a set of deeds which shows various owners and the name Rother Brewery, 1854-98.

Mappins would not have acquired the site, but took over the business.
"Market Place, Lyne, Greater Manchester, South Yorkshire." seems very muddled!
That's great information, thank you. Yes, I did kind of wonder how Rotherham became Lyne Greater Manchester then reverted back to South Yorkshire haha.
I know exactly where the brewery would have been and yes, it is very different now. Presumably Mappins would have bought the receipes, equipment and maybe ownership of any tied houses. I have found one tied house listing that brewery but its in Sheffield and the pub itself is no longer there.
Seems to have had official legal names but generally known as Sheffield and Rotherham brewery company. I am assuming that G G Grandpa worked for this brewery for the duration of his working life, as he seems to have worked in brewing from sometime in the 1870s through to his death. I wonder what the beer tasted like from that brewery - lost in the midst of time but chances are I suppose they would have produced the sort of bitter that was most common in Yorkshire at the time.
