Actually, the symbol and several others already exist and seem to be standardized. The "Duden", the authoritative source on German orthography, describes them in its section on typesetting practices, under the heading of "genealogical symbols". Besides the asterisk (born), the dagger/cross (died), and the two overlapping rings (married) it lists: wavy horizontal line (= baptized) a single ring (= engaged) two rings separated by a vertical bar (= U+29DE?) (= divorced) two rings joined by a horizontal line (= extramarital) two swords crossed (= died in combat) rectangle (= buried) urn symbol (= cremated)
The "married" symbol, by the way, typically differs from the infinity symbol, as it consists of two overlapping circles, not just circles touching each other. The "born" and "died" symbol, on the other hand, are clearly identical with the normal typographical asterisk and dagger.
The Duden also makes it clear that these are all for use in inline text ("können in entsprechenden Texten zur Raumersparnis verwendet werden"). I haven't got a scanner here, else I might put up a scan somewhere.
