.. jacob's fourteen daughters

..
`
b3141 ... thought i had a fairly decent knowledge of old testament.
Then i found sites
like http://www.jewishgates.com/file.asp?File_ID=1312 which contend
that jacob was the father of fourteen daughters ! !

it looks as though benjamin had TWO twin sisters while other sons of
jacob had one twin sister each. I've even seen some talmud-related
sites which have leah and rachel as twins.... probably frathernal
twins since the two lasses don't seem to have resembled each other.

.... a/ any additional data on this matter would be welcome

... ... b/ do we have any idea of names of benjamin's two twin
sisters ?

... c/ do we know names of benjamin's wives ?
