I've long loved Dorinda, so I'm already predisposed to enjoy the "rinda" component. The beginning brought both Isabelle and Isra to mind (came across the latter one a while back in a post where everyone was contributing middle name ideas to those who wanted suggestions, and the meaning of it struck me as kind of romantic). Are you pronouncing the first syllable as "is" or "iz" or "ees" or "eez"?
