I found his marriage - and possibly 3 children - John 'Rayley' 1736, Edward Ryley 1739 and Elizabeth Ryley 1743- all bap at Sandbach showing residence at wheelock - where I believe Edward Ryley was the Miller there.
Cannot be definitive as to the Edward Ryley paying land tax for a Mill in 1782 in Sandbach but it is quite likely to be the son born in 1739 bearing in mind life spans at that time.
Sometimes you just have ta accept that you have exhausted all resources!
