How to pronounce Neihnagbour?

Trying to locate an old elementary friend that moved to Toledo, Ohio around 1977-79. I remember how to pronounce her last given name but I can't seem to find the correct spelling for it anywhere. It sounds how it looks---knee/nay/bore---If you could please help me I would surely appreciate it. Thank you kindly~Kim
