The Walkers of Derby
In case it is of use to others tracing relatives in seventeenth-century Derby, I have put up a family tree for Henry Walker on Tribalpages. It has been put together through a mixture of information from wills and parish registers. So far I have managed to trace three generations back, and three generations forward, although I still have lots of gaps to fill in.
For the benefit of those Googling this page, here is a list of relevant surnames.
