Initially, Id be looking into the history of Whitemead Park (& house) as a possible candidate for a residence with staff locally

'In 1808, Parliament passed the Dean Forest (Timber) Act in response to a severe shortage of naval timber. The act included provision to enclose 11,000 acres (4,452 ha) and responsibility for its execution fell to a young, newly appointed, deputy surveyor named Edward MACHEN. He established his office at Whitemead Park'

reference 3a

Wikipedia suggests that, by 1860, the Colliery was owned by Sully & Company and in 1885 was sold to the Parkend & New Fancy Collieries Company. However, this may be an oversimplification. By 1878 James Sully was the only remaining partner in the Park End Coal Company and the Parkend Coal Company Ltd. was formed to acquire the collieries. The subscribers to the new company were James Sully and Richard Sully, both described as coal merchants from Bridgewater, Somerset, John Nicholls, also of Bridgewater, William Unwin of Oxford, John Bailey, Sydney Thomas of Parkend House, colliery manager and Thomas Thomas.
