When teaching history, I used to try to explain this to students- usually with little success. People have a hard time grasping how many people it took to make them... and how that gives us huge family trees.
When Rattlesnake Kate McHale was a young farmer near Greeley CO in the early 1900's, riding out to forage ducks, she dismounted to open a gate and a rattlesnake appeared. She had stumbled into a large den of them. While her 3-year-old son Ernie stayed on the horse, she killed at least 140 rattlesnakes. Kate used some of the skins to make a dress and shoes (now in the Greeley museum). Kate married and divorced six times, and was a taxidermist, farmer, midwife, and bootlegger.
