Facebook data scientists compared users listed as siblings with randomly generated pairs (of their respective name) to find out the most common sibling names. And the 10 most common pairs, when compared to chance, were: 1. Yvette-Yvonne: 37.4 times as often as expected 2. Faith-Hope: 31.4 3. Charity-Faith: 24.3 4. Jami-Jodi: 23.8 5. Gretchen-Heidi: 22.0 6. Charity-Hope: 21.2 7. Kelli-Kerri: 18.9 8. Latasha-Latoya: 18.5 9. Eileen-Maureen: 18.4 10. Colleen-Maureen: 17.0 Where’s Kourtney, Kim, and Khloe?
