Here I am clueless -I want your help

wikipedia syas that –
B?haspati is the son of Rishi Angirasa (according to the Rig Veda 4.40.1) and Surupa according to the Shiva Purana. He has two brothers named Utathya and Samvartana. He has three wives. His first wife Shuba gave birth to Bhanumati, Raaka, Archishmati, Mahamati, Mahishmati, Sinivali, and Havishmati, his seven daughters. His second wife Tara gives birth to seven sons and a daughter. Through his third wife Mamata, he has two sons, Kacha and Bharadwaja.

There is clear mention that Brhspati and Tara had seven sons and one daughter. But I have not found their names yet. Due to this I can not telly their name with the names of Four tribes of Tara I found in Ireland. Wikipadia mentions that there were Four Tribes of Tara – The O’Harts, the O’Regans (Ui Dron), Connollys, and the O’Kellys .
So if anybody help me to know the names of sons of seven sons of Tara then we can check the similarity.
pl help me to find ancient name.
