Here I am again replying to my own post!
I'm now 99% sure I have found the correct George WALKER, b. 1822. Via the FreeReg transcriptions from Parish Registers and the Internet Archive's Open Books, I have located several generations of Walkers with the right dates, baptisms, marriages and locations, giving me a totally different George WALKER with a wife who truly belongs in Axholm because her name is Bella HULME! So I have George WALKER (with Bella his wife) producing my great grandfather William WALKER in 1843; then his son William producing another William in 1873, who produced my father Edward Alfred in 1902. Before George came his parents, Thomas WALKER and Elizabeth RODEN and before them came Fowler WALKER and Phebe who must have been born around the 1760s. Every generation of these WALKERs has been born in Staffordshire, making the task of tracking them down very intricate. Now to track the maternal sides of these families- both HULME and RODEN seem to derive from Old Norse names, so that should be interesting. I'd love to hear from others who are tracing ancestors in the same region of England where the Norsemen were said to have made an early settlement.
