I've been working on a Northumbrian divergence point, sometime before 642, that incorporates much Ioanian & Dal Riata influence. I'm hoping to establish a grounded timeline that reflects population and resource reserves for a Northumbrian overlordship or at least a continued subjugation of Mercia.
My immediate wants would be to understand post-Roman roads, earthworks, and harbors in Northern England that would be readily available for rehabilitation or of continued use. Where were the main routes, and of how many were still in use so many centuries past occupation? Accurate maps would be great. I would also want to know of evidence of how much off-shore navigation occurred with Clinker (not currach) type ships.
Does anyone have any good sources, backed up with archeological studies? I really want to know what could have been available more so than what was recounted by early historians. Any help is appreciated.
