href="https://en-m-wikipedia-org.translate.goog/wiki/Ahnentafel?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en-GB" title="Ahnentafel">Ahnentafel</a>, also known as the <b>Eytzinger Method</b>, <b>Sosa Method</b>, and <b>Sosa-Stradonitz Method</b>, allows for the numbering of ancestors beginning with a descendant. This system allows one to derive an ancestor's number without compiling the complete list, and allows one to derive an ancestor's relationship based on their number. The number of a person's father is twice their own number, and the number of a person's mother is twice their own, plus one. For instance, if John Smith is 10, his father is 20, and his mother is 21, and his daughter is 5.</p> <p>In order to readily have the generation stated for a certain person, the Ahnentafel numbering may be preceded by the generation. This method's usefulness becomes apparent when applied further back in the generations: e.g. <i>08-146</i>, is a male preceding the subject by 7 (8-1) generations. This ancestor was the father of a woman (146/2=73) (in the genealogical line of the subject), who was the mother of a man (73/2=36.5), further down the line the father of a man (36/2=18), father of a woman (18/2=9), mother of a man (9/2=4.5), father of the subject's father (4/2=2). Hence, <i>08-146</i> is the subject's father's father's mother's father's father's mother's father.</p> <p>The atree or Binary Ahnentafel method is based on the same numbering of nodes, but first converts the numbers to binary notation and then converts each 0 to M (for Male) and each 1 to F (for Female). The first character of each code (shown as X in the table below) is M if the subject is male and F if the subject is female. For example 5 becomes 101 and then FMF (or MMF if the subject is male).

This used the following: f = father m = mother so = son d = daughter b = brother si = sister h = husband w = wife c = cousin. By concatenating these symbols, more distant relationships can be summarised, e.g.: ff = father’s father fm = father’s mother mf = mother’s father.</p> <p>We interpret “brother” and “sister” to mean “same father, same mother” i.e: b = fso and mso si = fd and md. Some cases need careful parsing, e.g. fs means “father’s son”. This could represent (1) the person himself, or (2) a brother, or (3) a half-brother (same father, different mother). Very often, terms are synonymous. So m (mother) and fw (father’s wife) might refer to the same person. Generally m might be preferred – leaving fw to mean a father’s wife who is not the mother. Similarly, c (cousin) might mean fbso or fbd or fsiso or fsid, or indeed mbso or mbd or msiso or msid, or several other combinations especially if grandfather married several times. Brother-in-law etc. is similarly ambiguous. Other genealogical notations have been proposed, of course. This one is not claimed to be optimal, but it has been found convenient. In Bibby's usage , the “home” person is Karl Pearson, and all relationships are relative to him. So f is his father, and m is his mother, etc., while fw is Karl’s father’s second wife (who is not his mother).</p> </section> <div class="mw-heading mw-heading2 section-heading"
