I've created two military categories for War of 1812, that the project team might want to review for compliance with your standards. They are both for Elijah Timmons (Timmons-588).
1) I created Category: Renick's Regiment, Kentucky Mounted Volunteer Militia, War of 1812, which complies with the posted instruction to first use the name of the commanding officer instead of the unit's number...... I included "Volunteer" in the name but there's no consistency in the existing categories on that..... Also, there's a current category called "Kentucky Battalion Mounted Volunteers, Rennick's, War of 1812" that I didn't use because it's name doesn't comply with the instructions. I didn't delete it though.
2) I went further off the menu on this one. While someone obviously spent a lot of time and thought creating the posted list of Kentucky Regiments, Wilcox's Regiment, Kentucky Volunteer Militia, War of 1812 wasn't included. I have a military general index card for my ancestor's service in this unit https://www.wikitree.com/photo/jpg/Timmons-588-4 but I couldn't find an existing category that seemed to fit. Again on this one too, should "Volunteer" be in the name?
If you prefer that I contact the project team before creating categories, let me know....... but I probably need the practice and don't mind if my categories need to be deleted.
