The declension of the 3rd person plural is identical
with the declension of the 3rd person singular feminine.
This would be quite obvious, because they have the same
possessive pronoun: ihr
*
In common language, the Genitive of the substantival possessive
pronoun is not used. There is another form of a possessive
that could be used (der ihrige, die ihrige, das ihrige),
but it sounds really antiquated. If you want to form
a Genitive of ihre
it is mostly done like in English.
|
Das
ist der Schlüssel von ihrem (Auto etc.).
This is the key of theirs. (their car etc.)
|
|
|
The same could be said with a real
Genitive and ihrige
(it's just not used commonly):
|
Das
ist der Schlüssel des ihrigen.
This is the key of theirs.

Example:
die Schachtel (= box) possessed object => feminine,
singular |
|
Ich
sehe meine, aber ihre nicht.
I see mine but not theirs. |
|
|
Example:
das Kleid (= dress) possessed object => neutral,
singular |
|
Du
kannst mit ihrem hingehen.
You can go with theirs.
|
|
|
Example:
die Häuser (= house) possessed object =>
neutral, plural |
|
Ich
sehe meine, aber ihre nicht.
I see mine but not theirs.
