|Daitch-Mokotoff Soundex System|
The variations in latin script of the same original ashkenazic surname are generally due to the geopolitical changes that took part in the beginning of the twentieth century in the pale of settlement of the Russian Empire, added to the fact that most of the surnames were written for the first time with cirilic (in russian) or hebrew script (in yiddish). Also contributed the fact that, due to the persecutions, in many cases people emigrated without documentation.The soundex system is based in calculating a code of six numbers, where each number represents a sound or a vocalization. Each number is obtained from a table and a group of several rules. The table is built in a way that you will always obtain the same number from different letters or group of letters that have similes sound, either in the same or different languages.
> For example, the group SCH and the group SZ give as a result the same number, 4. That is because in german the group SCH is pronounced (SH), as the group SZ in polish. The letters V, B, W and F produce the same number 7, due to its similar pronunciation. The groups AI, EI and OI, are codified with the same number because they are alternatives of pronunciation.According to this, if two surnames have the same Daitch-Mokotoff soundex code (six digits), they may be the same original surname with a variation in the latin scipt. Nevertheless you must know that not all the surnames that share the same code are necessary a variant of the same surname.
