That's interesting!
There appears to be a John and Ralph born or christened at St Chads over around 1730's at St Chad's, Over, now you mention a Samuel.
I picked up an Oakes family tree starting in 1675, Samuel (Cheshire), who had son John (Over,1698), who had son John (Over, 1727), who had, in turn, John (Sandbach, 1749), who had sons John (Over, 1770), William (1776) and Thomas (1781).
Incidently, Davenport is close to Holmes Chapel, which is near Middlewich.
