Expression in lemon

Hi,
I am learning a declarative way to express a word to ontology concept. I
found lemon  more suitable for the task.How to express the word "twins" in
lemon? We can defined as people with the birth date and same mother. It can
be more than 2 persons (according the language and culture). Any suggestion
is welcome. Thanks.

Regards
Olivier
