1. Genetic and Medical Genealogy: 6:30 p.m. Friday at the Midwest Genealogy Center, 3440 S. Lee's Summit Road, Independence.

A former member of the KU Hospital Genealogy Advisor team, she will share how you can become your own health advocate by charting your family’s medical genealogy. This is not a medical presentation, but one more phase toward gathering family and ancestral data. It’s free, but registration is required online at mymcpl.org/events. For questions, call 816-252-7228.

2. Snake Days: 4 p.m.-4:30 p.m. Thursday at George Owens Nature Park, 1601 S. Speck Road, Independence. Get to know two mild-mannered corn snakes and a large but shy great plains rat snake.

3. History presentation: 10:45 a.m. Friday at the Palmer Center, 218A N. Pleasant St., Independence. The National Frontier Trails Museum will give a presentation on African-American pioneers. On every western trail, from the Lewis and Clark Expedition to the California gold rush, African-Americans made a mark on the history of western expansion. The journey west was difficult for all who traveled the trails but, for African-American pioneers, the discrimination and oppression they faced made their contributions even more exceptional. Hear the stories of some of these individuals and learn what it took for them to make new lives for themselves in the West.
