Using records at the Cheshire Family History research centre at Alderley Edge I was able to get a copy of the record of John and Martha's wedding at St Mary's Cheadle, and even better, also found the record of Alexander Gradwell (John's father) and Charlotte Lowndes' wedding in 1813 and Robert Gradwell/Gratwell (Alexander's father) to Martha Jennings in 1789, both at St Mary's church, Alderley, plus a host of baptisms, great for cross-referencing. This resulted in us finding Alexander and Charlotte's grave at St Mary's, hidden under a carpet of yew tree needles. Thanks for your help, which put me on the right track to discover all this. We are now trying to find some record of Robert's baptism as there are no earlier references to Gradwells at Alderley, suggesting that Robert came from outside the area and settled there.
