Meaning: ⲧⲗ̄ⲗ-, 'God' + ⲏⲩⲣⲁ (unidentified). Perhaps a misreading or misspelling is at stake and we should read ⲧⲗ̄ⲗⲛ̄ⲩⲣⲁ instead, which could be analysed as ⲧⲗ̄ⲗ-, 'God' + -ⲛ (genitive) + ⲟⲩⲣ-, 'head' + -ⲁ = 'the head of God'?
Meaning: most probably cognate with the modern Bedauye 'ti=liːli', 'the eye', where 'ti=' is the definite feminine article and 'liːli' is 'eye' (pers. comm. M. Vanhove & Muhammad-Tahir).
Meaning: ⲧⲟⲥⲥⲓ-, probably cognate with the Nobiin ⲧⲟⲥⲥⲓ, 'inundation period' + -ⲛⲉ (abstract substantive formant) = 'flood, inundation period'.
The name probably refers to the time of birth of the person.
