Re: Possession and genitivity

I've changed my genitive rules as follows:

Possessive genitive:
- noun: -us
- adjective: -an (accusative)
ôkro ytibus mezan
field-SUB club-POS large-ACC
the large club's field
(both alienable and inalienable)

Partitive genitive:
- noun: -ön
- adjective: -as (dative)
muriti waþönön bêlas
more water-ABL blue-DAT
more (of/from the) blue water

Accusative genitive:
- noun: -ü
- adjective: -as
adujge þu þöbiþü
accuse-1PERS you-ACC theft-ACCGEN
I accuse you of theft

Executive genitive:
- using jôn (by) with dative case (-um (noun) and –as (adj))
taþo jôn xátsum šaras
arrival:SUB by cat:DAT grey:DAT
the arrival of (by) the grey cat

...but how should I use more than one genitive form in the same sentence,
like _the arrival of several cats_ or _I accuse several people's children_?
