The thing that sticks at the back of my mind Shaun were those newspaper reports you posted with John B LLoyd as manager at the General Cabriolet Conveyance Company in 1836. Would a 17yr old hold this position? The issue is, we don't have anything as yet to help with identifying John except the two birth entries with a 12 yr gap

But then from that 1838 newspaper entry, we have John having to apply to his Guardian for release of funds - not sure of the terminology of those times. Is the term guardian like a trustee of an estate or does this imply a custodian of a younger person's interests?
The only potential entries we have found so far for John is potentially that 1851 census entry (right birth place, c. 1807 birth, likely occupation of commercial traveller - except he shows as unmarried

). Also, the 1871 census entry that Jorose found at the Poorhouse in Battersea. We need something to be able to identify him properly.
Maybe one way forward that is verifyable is to follow up on a poor relief application/admission for the John Lloyd who shows as an inmate at the Wandsworth and Clapham Union Workhouse in 1871. I know that records for admissions for here are only available at the London Metropolitan Archives. If they can be found, it would help to either confirm or eliminate the John B Lloyd b. 1807 to Benjamin and Elizabeth Collins.
