Its all very confusing isn't it!!I have Richard Hunsley born 1666, whose father is John Hunsley.Richard is the eldest brother of my 7G Grandfather Charles Hunsley, born 1681.My line then descends through John, then William, then John then William born 1800.
John, William, Richard and Thomas to name but a few seem to crop up in all generations of the Linconshire Hunsley's.So you may well descend from Richard bd 1666, but there is no guessing which names link him with your William bd abt 1800.
My Charles Hunsley (brother of Richard bd 1666) and my William Hunsley bd 1800 have 3 whole generations in between them.So I think it is highly unlikely that you are only looking for one missing generation!!!
Will email privately the line I have, showing where Richard fits in.
In the meantime, I wish you lots of luck in making the connections you are looking for.
