This week’s Genea-Musings: Saturday Night Genealogy Fun mission is ‘Ahnentafel Roulette.’ This mission has three steps: Figure out how old your great-grandfather, or other ancestor, would he be if he had lived. Then, divide this number by 4 and round the answer off to a whole number. This is your “roulette number.” Use your pedigree charts or your family tree genealogy software program to find the person with that number
