Though little did I know, thanks to the US Census Bureau and Social Security Administration, we're approaching that version of a future. Check the third entry on the listing here:
Social Security Data
The location verifies we've got the correct man. (Although, apparently there was another person by that name from Ohio.) It shows the date of birth for Mr. Kiggins as March 06, 1867. This gives me the date of his 100th birthday a century later. I was able to confirm that, as the article stated, the date was a Monday. If I recall correctly, the weekly paper used to come out on Wednesdays. This would mean that yesterday's entry probably ran in the March 8, 1967 issue.
I learned that he lived a bit more than two years after the celebration contained in the article.
Additionally, his social security number was 001-36-5160. Yet when President Roosevelt signed the Social Security Act in 1935, Sylvester Kiggins would've already been 68 years old.
How that for detective work?
