What does Ada mean?
Igbo, 'first-born daughter.' Ada is a title-like name marking the eldest daughter and heads many compounds, e.g. Adaeze ('princess, king's daughter') and Adaobi ('daughter of the household').
What does Amara mean?
In Igbo (Nigeria) 'amara' means 'grace', a short form of names like Amarachi ('God's grace'). The same form appears elsewhere with other senses (Sanskrit 'amara', immortal; a poetic Latin/Italian echo of 'love'), but the best-attested meaning is the Igbo 'grace'.
