Thank you Molly C for your helpful comment, and Alan, thank you for the obituary of WC Boyd. It does sound to me that being a Manchester Warehouseman allowed one time to lead a very enjoyable life pursuing one's interests, without the actual work impeding this too much.
The Grange (97 Crossbrook Street) was and perhaps still is being used as a nursery. I note that it was built about 1900 so must have been a new house for the Boyds. This isn't a very good photo but gives an idea of its appearance
Are you a relative of WC Boyd, Alan?
