Directories and records list, John James and John James Grohe as watchmakers.
John Grohe was an established London Clockmaker, who died in 1872, in the years following his death he is listed as working in various places.
Around 1910, his entry has changed in trade directories to ‘James Grohé, watchmaker, late 3A Wimpole St. & 24 Wigmore St. removed to Smith (Bolton), 26 Duke St. Manchester Sq. TN755 Paddington.’ This entry continues to be recorded through 1920.
1914 Trades Directory
The Smith above presumably related to Smithills, Bolton.
A watchmaker called Typke who died in 1909 had moved into his premises and also used the Grohe name. It is unclear who continued to list James Grohé’s details in the trade directories for the next 11 years, or why.
