Excellent explanation!
May I add something jokely but sometimes sorrowfull, really true things:
My name by the Roman Catholic register is Reich, Lajos Iván Antal Gyula. (by the state registers only Kalos; it is also a Hungarian speciality: the register of Churches and the state need not be absolutely the same)
When I was born, the war havoced (???) in Hungary, The Soviet army was inside the country, the people had feeling "the World's end" and of course the baptiser company, who tokk me under the sacrified water was complete drunken (also the priest) so I got my names
1st the Lajos naturally after my father
2nd the Ivan maybe gives some protection for me in front of the Russian soldiers
3rd Antal, after my Godmother
4th Gyula after my Godfather, otherwise the name Gyula was traditional in our family.
An other thibg.
The families saved the namegiving tradition (written by Janet: after father, after mother) that it happened many times, that when the boy, or girl died, the newborn boy or girl got the same names! But in these situations was not rare, the second nameuser got a second name, to teke differencies (and by suprstition)
Otherwise the namedays in Hungary are celebrated much more. like the birthdays, which are celebrated usually only inside the families.
