Hereditary number: calculation and meaning in numerology

Your birth name, as it appears on your birth certificate. The hereditary number speaks of what was handed down to you, and that name is the one that carries it. A name taken through marriage or chosen later tells of another stage of your life: some schools calculate it separately, as an added color, but it never replaces the original name.

You add up all the letters of both names, as if they formed a single one, then reduce the total. Martin-Durand thus gives 30 + 26 = 56, then 11. The order of the names changes nothing in the result. Some people also calculate each name separately to see what each branch contributes: that is a complementary reading, but the hereditary number remains that of the full name.

Yes, as long as it is part of the name on your civil record: de, du, Le, La, Van, or Mac are added like the other letters. Only spaces, hyphens, apostrophes, and accents are ignored. Le Goff is therefore calculated on LEGOFF, and D’Arcy on DARCY. Removing the particle would give a different number, which would no longer match your birth name.

Yes, everyone who carries the same birth name shares this number: brothers, sisters, cousins from the same branch. What changes is how each person lives it, since each pairs it with a first name and a date of their own. In a hereditary 8 sibling group, one keeps the vacation budget, another avoids any question of money: the same inheritance, two responses. A half-brother who carries a different name will have a different number.

Yes. Rousseau gives 29, then 11; Aubert totals 22 right away; Vincent reaches 33. These totals stay whole, whereas Fermier kept only 11 and 22. A master number name does not put a family above others: it signals a more demanding inheritance, quite often lived first through the digit it reduces to, before its own dimension takes shape. The pages for values 11, 22, and 33 detail this double reading.

The hereditary number counts only the surname; the Expression number adds the first name and the surname. The first describes baggage received, the second the personality you show once that baggage is mixed with your first name. For Hugo Roux, the surname alone gives 24, then 6, while the full name gives 48, then 3: a lineage turned toward caring for its own, and a person who presents themselves first through speech and social ease.

Yes, both expressions designate the same calculation, the reduced sum of the letters of the surname, and you will come across either one in numerology books. Differences between sites lie rather in the method: some start from the name in everyday use, others reduce 33 to 6 following the rule of only 11 and 22. Here, the birth name always serves as the basis and all three master numbers are kept.

You first bring each letter back to the basic Latin alphabet. The umlaut and the cedilla drop away: Müller is counted as MULLER, giving 27, then 9. Letters absent from French are transcribed: the German ß becomes SS, the Scandinavian Ø an O, the Œ splits into OE. A two-letter name poses no particular difficulty: Li totals 12, then 3, and reads like any other hereditary number.

It has no scientific basis: no evidence shows that a surname shapes a character. The calculation itself is reliable in the sense that it always gives the same result for the same name. Its value depends on what you draw from it: a framework for reflection to spot what you received from your family and choose what you keep. It makes no predictions and judges no family.
