The last entry on the 1911 census summary book is the 'Lemonade Factory' Well Strand. Unfortunately no individual is recoded with the property.
The only reference in the newspapers I can find is from the Morpeth Herald 18th May 1901:
"The Rothbury Aerated Water Company will thank the person
who took the HORSE SHEET from the Farmyard at Low Trewhitt
on Sale Day, May 1st, to return the same to Well Strand, Rothbury."
