Teressa,
The places you are searching are all online family trees, you should search actual sources instead. The chart was researched and sourced from numerous volumes of medieval history that Ky has collected over a number of years and utilizes when making his charts. A number of these resources are available at Clayton Genealogical Library in Houston, and likely in other locations as well. Worldcat may help you locate resources at a facility near year.
You may want to join a wikitree project with a focus on the ancestors/timeframe of personal interest to you.. Also, rather than tag my name, tagging the ancestor in your tree that you referenced in your Ashby line, that you are working on would, I think, be more helpful, as I'm not sure who you are wanting help with specifically. Alternately, you may want to contact Ky and order a chart for yourself, providing him with what you have documented of your own tree. Hope this helps!
