Alan Your analysis demonstrates that, thanks to you, Don and ......., great strides have been with the 19th/20th Century K/Nibb/s family trees: there will now follow a steady growth with increased connections stimulated by the web site/s and the established data base. For me the great challenge, the unattainable Holy Grail, is the linkage of the earlier trees. I recall you have already undertaken geographical analyses but is there any mileage to be gained from a (post-Wimbledon/Euro 2004) pursuit of the total population of pre-1700 K/Nibb/s? Can we just list them- not worrying about connections at this stage- every pre-1700 waif and stray. How many would there be? What geographical clusters? The areas where there are none? None because there are none? Or because no research has been done there? Can the call, therefore, go out for any pre 1700 K/Nibb/s, ticking off the Record Offices that have been scoured and those still to do? No urgency- just a separate and discreet mission, where this head count can be enjoyed and celebrated. A waste of effort? Already undertaken? John Knibbs
