I like the idea of twins/siblings Kajal and Keturah (kohl and incense). I recently listened to an audio of a native Hindi speaker saying Kajal. It sounds like cudgel except the vowel in the first syllable is like the a in father: KAH-jəl.
Sounds like "cudgel", a thick stick used to beat people over the head! If you like the meaning, which is "kohl", the black eyeliner Middle Eastern and Indian people use (and once used by the Ancient Egyptians to create that "Egyptian look"), then just name your baby, Kohl or Cole!Go to http://www.kamat.com/kalranga/dances/3352a.htm to see what Kajal really is -- check out those eyes!
