1 - Is a patronymic/Matronymic name a surname or given name ?
For gramps this name is stored in the surname field.
2 - When we use filtering for report creation, if we use " Given names replaced, and data removed",
is the following snapshot correct ? Living surname is a patronymic/matronymic surname.
For my cases, Belgium, 16th & 17th century, patronymics seem to be more used as a second given name rather than a surname. For Russian patronymics, I’m not qualified to answer, but they look like they’re not considered part of the surname [please correct me if I’m mistaken]. I’ve chosen the following name format in preferences: “Primary[sur] Primary[con] Notpatronymic, Given Patronymic[sur] Suffix Primary[pre]”, since this seems to best match my requirements. So “$Surname”, [Living given name] [Living patronymic/matronymic] was what I was expecting here as well, rather than "$Surname [Living surname], [Living given name]. To me, it would also make sense that if the father is deceased, that you can then show the patronymic, since their full name will already be shown, and the patronymic can be fully derived from the father’s name. Likewise for the mother + matronymic.
