Language 1: Kiowa (ISO: kio)
Number of Speakers: 400
Likelihood of finding text: High (see https://archive.org/stream/rosettaproject_kio_vertxt-1#page/n0/mode/2up)
Spoken in west central Oklahoma.
Kiowa appears to be synthetic or even agglutinative, as many morphemes seem to be able to combine into a word that can have the meaning of an entire proposition. (Inferred from the text linked above.)
Language classified as "moribund" by Ethnologue.
Language 2: Gikuyu/Kikuyu (ISO: kik)
Number of Speakers: 6,623,000
Likelihood of finding text: Guaranteed (see http://www.language-archives.org/language/kik)
Spoken in various parts of Kenya.
Gikuyu seems to be mostly synthetic, although I am not certain. Texts (such as the one linked above) can have somewhat long words that appear to be formed of numerous morphemes.
Major concern is that resources might already exist for Gikuyu given its size. I cannot, however, find any significant resources.
Language 3: Lakota (ISO: lkt)
Number of Speakers: 2,000
Likelihood of finding text: Very high
Spoken in parts of Nebraska, North Dakota, and South Dakota.
According to wikipedia (https://en.wikipedia.org/wiki/Lakota_language), prefixes and suffixes exist in Lakota, suggesting that it is not analytic and probably synthetic.
