Well, the Penni are known to be the Avari who inhabit the Vales of Anduin and Woodland Realm. And all the other named clans are said to have lived in Eridaor and the Vale.

""… *kwendi. This word, as has been shown, did not survive in the Telerin languages of Middle-earth, and was almost forgotten even in the Telerin of Aman. But the Loremasters of later days, when more friendly relations had been established with Avari of various kinds in Eriador and the Vale of Anduin, record that it was frequently to be found in Avarin dialects. These were numerous, and often as widely sundered from one another as they were from the Eldarin forms of Elvish speech, but wherever the descendants of *kwendi were found, they meant not 'Elves in general', but were the names that the Avari gave to themselves. They had evidently continued to call themselves *kwendi, the People, regarding those who went away as deserters - though according to Eldarin tradition the numbers of the Eldar at the time of the Separation were in the approximate proportion of 3:2, as compared with the Avari (see p. 381). The Avarin forms cited by the Loremasters were: kindi, cuind, hwenti, windan, kinn-lai, penni. The last is interesting as showing the change kw > p. This might be independent of the Common Telerin change; but it suggests that it had already occurred among the Lindar before the Separation. The form penni is cited as coming from the 'Wood-elven' speech of the Vale of Anduin, and these Elves were among the most friendly to the fugitives from Beleriand, and held themselves akin to the remnants of the Sindar.""
