Other than Jone in 1683 when Peter was born, I'm not finding any other Hobbs in Market Lavington prior to this date.
I do find Hobbs in Stert, Bromham, Paulshot, Inglesham, Rowde, Aldbourne, Maries, Heytesbury, St Peter And St Paul, Marlborough, Calne, Malmesbury.
Locations determined by ref to IGI (so some will be individual entries rather than transcribed files).
The largest concentration circa 1660 is in Aldbourne.
I'm wondering if, as it appears, Jone was sent away from home to have Peter as no father is listed.
That being the case she must be linked to one of the other family groups in Wiltshire, but which one?
