Hi Chris,
Thank you for noticing Katherine's profile! It certainly took some time to research, given that I was a junior in high school at the time I wrote it :) Thankfully, though, as I am now studying a dual BA/LLB, I've gotten research down to a fine art!
In regards to the source citations, each one was written in accordance to WikiTree guidelines, and in regards to the Richardson citations, following the format set out by the Magna Carta Project.
I appreciate that you may favour a genealogical style of profile rather than a biographical one, but I worked hard to include elements of both genealogy (her parents, her spouse, and her children) as well as contextual elements of her life. Not as "fluff", but because I believe that context is important when we consider historical profiles (notable or otherwise) when we are attempting to learn about their life. For example, I consider Roger's ever-changing role in English society as important to Katherine's life and the circumstances which led to her marriage, because the marriage dispensation was granted in direct relation to a dispute over land between the two.
I do not expect that we'll agree on one side or the other on this, though I fully respect and understand your point of view! The only comment I have left is that, whether a biography aligns with your preferences or not, I hope that if/when you receive your Pre-1500 Certification that you don't intend to make such drastic changes to a fully-fleshed biography like the one on Katherine. After all, differences in opinion aside, this biography for example is fully written with detail and backed-up by sources, and I would feel incredibly disrespected if you then went and changed something which I put a lot of hard work into :)
Regards,
Amelia
