It's 3 years since you posted your message. Are you still out there? I have some more information on Jonathan Fildes who turns up on a collateral line to one I connect to published in Joseph Foster's Pedigrees of the County families of England Vol 1 Lancashire London: Head, Hole 1873. Whether this connection is real or was just wishful thinking on the part of the Manchester Fildes is another matter, but Jonathan was clearly very well known in his day. Get in touch and I'll send you what I have.
