Hello Simon
I have no definitive answers, just comments.
I believe your Susannah is indeed the Susannah chr 1751, daughter of John, a labourer of Honley, and you have correctly identified her three siblings Sarah, William and John. The John Kenworthy/Hannah Wilson marriage is beautifully timed a few months before the birth of Sarah in 1745, so I would be happy accepting Hannah Wilson as Susannah's mother. The only birth I can see for a likely Hannah Wilson is the baptism at Kirkburton 23rd July 1718, daughter of John Wilson of 'Mithorn Brigge', Wooldale. There is a John Kennerley chr 29th November 1718, son of John of Marsden, and another 8th August 1718 at Slaithwaite, son of an unnamed person of Lingards. John Kennerley of Linthwaite christened a daughter Martha on 31st July 1718, just to add to the confusion of Johns. It must be remembered that the Almondbury records were very badly kept 1703-27, with only, in my estimation, about a third of events being recorded (unless the population of the parish suddenly tripled in 1727 when a new vicar arrived!)
The birth of your Thomas was history repeating itself as an Abraham Kenworthy was christened in Honley 19th August 1733, son of Susan Kenworthy, the father being named as Abraham Lockwood.
Regards,
Lesley
