Pedigree mapped5 generations

90%56 of 62 ancestor slots are recorded.

Computed from the identified parent links recorded in this 5-generation window, including shared ancestors’ recorded inbreeding. Unknown founders are assumed unrelated; this is not a DNA measurement or certification of the source records. Displayed percentages are rounded. 6 of 62 slots in this pedigree are still unknown, and an unknown ancestor cannot duplicate — read a low coefficient as missing evidence, never as a proven outcross.
