Hi Trent,
I have all that information inserted into an EXCEL spreadsheet and I do a criteria search on it when I'm looking for a specific name, place or date. It took me a long time to create the spreadsheet but it is easily maintained and now I just go into randomly and add or correct anything I need to. Besides the alphabetical spreadsheet, I've also created a few others that rank things like oldest to youngest, order of the survivor deaths, etc. I've not done one to capture the information in a calendar type arrangement like you're doing, but I'd think just a plain excel spreadsheet starting on January 1, and running the full 365 days would work well--it would just take a while to create it.
Thanks for your efforts--always enjoy reading whose events fall on the same anniversary.
Sometime you'll have to come to South Carolina and let me show you the "collection."
My best,
Phil
