Every human being is the result of countless (but finite) generations of parents, and the number of ancestors is easily computed:
| 8th generation | -200 (years ago) | ancestors: 256 |
| 9th generation | -225 | ancestors: 512 |
| 10th generation | -250 | ancestors: 1,024 |
| 11th generation | -275 | ancestors: 2,048 |
One is almost certain to find “interesting” lines of ancestry, which become of the focus of one’s research and interest. Taking 02/02/2020 as a symbolic starting point and looking at ancestors of interest, our genealogical interest has focused mainly on:
- Cleenewerck / Cleenewerck de Kiev / Cleenewerck de Crayencour (a different branch), to 1500s
- Fasnacht / Fosnaugh, to 1400s
- von Erlach, to 1100s
- Lentulus, to 1500 and by tradition to ancient Rome
