Stubbins Farm was probably simply named after its original owner. (i.e. a Mr Stubbins).
The surnames Stubbins, Stubbings and Stebbings are all derived from the Old English 'stybbing' (or Mediaeval English 'stebbing') being either a topographic name for someone who lived near a clearing in a woodland or a habitation name for someone who came from some minor place which derived its name from its proximity to such a clearing (or to a tree stump, which was 'stubb' in Old English).
The foregoing is derived from 'The Oxford Names Companion' although, in their 'Dictionary of English Surnames', Reaney & Wilson refer to the possibility that such surnames could also refer to the height of a person (with the Old English 'stybbing' being taken to mean 'the stumpy one') as well as agreeing that it could also mean 'dweller by the cleared land'.
The Oxford Names Companion refers to 'Tongue' or 'Tonge', when included in place names (as in the villages of Tongue and Tonge, in Highland and Leicestershire, respectively) as referring to a tongue of land. (i.e. a narrow strip of it). 'Scrogs' (which may originally been 'Scroggs') is possibly the name of the landowner. ['Scroggs' is a habitation name, meaning 'dweller by the brushwood'].
So 'Long Tongue Scrogs Lane' may well refer to a long, narrow strip of land that was owned by a Mr Scroggs.
