I've worked on the Great People list some more:
Great Engineers have been added - mainly architects, and a few inventors. 32 names - 7th c. to 16th c. I was getting nowhere until I discovered that medieval architects are more generally known as master builders and master masons.
Great Saints have been diversified - a second look at all those canonized saints made me realize I had neglected all the other religions out there. Now there are 56 saints - maybe too many, but they are a pretty diverse bunch!
Great Merchants have idled - I found a few new Great Merchants, but reclassed some inventors to Great Engineers. New count: 23. [@Craig Sutter: I looked up Erik the Red and Leif Eriksson - they sound more like settlers than traders, but they're definitely not nobles. They are now merchants!]
Great Nobles, Great Scholars, and Great Artists have grown - I met some interesting non-European figures while researching diversified Saints and Great Engineers.
Finally, anybody born before 500 has been deleted to maintain accuracy given the "[Great Person] has been born in [Kingdom]" message.
I wanted to attach the spreadsheet, but apparently, .xls files are prohibited. Anybody know a work-arounds to attach an .xls? Here is a .pdf instead. I can email the .xls to anybody who's interested - let me know.
Any editions are welcome! -Laina
EDIT: 12.19a - I forgot to mention that I reviewed the mod and vanilla .xml and incorporated great people names as appropriate. Many were dupes, I should of thought to start there. D'oh!
