The evidence supporting this is the fact that some Suba groups speak languages similar to Luganda, Lusoga and the Luhya.

Those groups from Uganda are mostly concentrated in Rusinga and Mfangano islands with small pockets of them being found in mainland Kenya.

Suba clans in Suna include Simbete, Sweta, and Wiga; and they have a clear and distinct ancestry that goes back to forefathers who crossed red Sea from Misri as illustrated below: Ragwe<--Siora<--Montheya<--Girango<--Musubaabs Their language is also distinct and very different from the Olusuba language spoken by the Abasuba of Homa Bay County.

There are also people in Tanzania (Tarime, Musoma and Rorya Districts, Mara Region) who call themselves Suba, and are part of the Abagirango since their language and cultural heritage is the same.

This group includes the following clans: Waware, Awakiwanga (Kaswanga), Wanyama, Waregi, Awamasengere (Kamasengere), Wasaki and Awangoze (Ngodhe), while others were called the Awibuang'ano/Awaivuang'ano (Mfangano/Fang'ano).

This group includes Wakula, Wasamo, Wagimbe, Wiramba who are related to Awakiimba (Kakiimba), Awisokolwa and Waozi.

Other groups also poured into Mfangano due to the pressure from advancing Luos in Central Nyanza especially in areas around Imbo Naya.

The clan that predominantly lives the closest to Lake Victoria and is the bigger of the sub groups is the people that go by the name Awigassi or Gwasii and they happen to reside upon the Gwasii Hills, Gwassi and Wakula are related since their forefathers Kiboye and Witewe were brothers before escaping to the east after a revolt in the Bagandan Kingdom in the year 1700.

Today many people in the islands and the highlands subsequent to Lake Victoria still retain the original Suba dialect that is the Olusuba that is closely related to the Ganda language, and Lusoga although it is heavily influenced by the bigger Dholuo and Kuria in some areas through interaction.

The Suna have however integrated clans originally part of the Olusuba speaking Suba such as Waware, Wiga and Kaswanga into their various sub-groups.

The Suna people are the Abagirango or Girango people who call themselves Abasuba because Girango had a son named Musuba (Suba) and not because they are related to the Olusuba speaking Suba of Homa Bay County who are descended of migrants from Buganda and Busoga that entered Kenya through Rusinga and Mfangano Islands by boats.

Clans of Suna people; Wasweta, Kadika, Wiga, Wanje, Katiga, Kakaeta, Kanyameda, Wasimbete, Wakwera, Wanyara, Kamn'go'ngo 2010.

Suna Girango circumcision process is very similar to their neighbors the kuria even the saro names, for instance, Nginaro, Misungu, Gitang'osa, Kirina, etc.

During funerals there were gifted elders who would carry Engawvo a type of shield and a long spear and Chant around the homestead while adorned with twigs.

The education system is teaching English and Luo to the newer generations of Suba children thus impairing the possibilities of the language to come back.

Many blame the elders as they do not take proper measures to ensure the language's existence by teaching their young ones from an early onset.

The biggest concern deriving from the pressures of reviving the language is the fear that their children will begin to build an identity crisis while attending school, considering that it is taught in either English or Luo.
