After many years of searching I have finally confirmed a family legend of a connection to the Isle of Wight

I have no knowledge of how the record situation for this area works - no idea where best to look.
I have tracked them back to James Chiverton/Cheverton born 1742 to John and Grace in Newchurch.
1728 5 Sep John Cheverton married Grace White Brading.
I have also come up with a will at the TNA Kew for a Grace Cheverton widow of Brading - not sure if it is too late to be the same Grace
Reference: IR 26/412/13 - Abstract of Will of Grace Cheverton, Widow of Artingshote Farm in the parish of Brading Isle of Wight, Hampshire. Proved in the Court of Winchester January 30 1796
Any hints or advice as the best way to track down this family without having to travel gratefully accepted.
