2018, and I am giving a shot at Amy Johnson Crow's "52 Ancestors in 52 Weeks" project.
So, the third challenge is "Longevity".
Here is my take on longevity. From my data base software, a Statistics Report produces the following information and LOTS more. These sections concern longevity.
After looking at these numbers, I am going to have to go review those "longest" male and female lifespan peeps. I do have a few that I am fairly sure died when over 102 years of age. But, seriously, 104 and 106? OHHH, review time!
