Three Harvard and Radcliffe seniors have received Michael C. Rockefeller Memorial Fellowship grants for 1967-68.

The students are Suzanne E. Young of Edmands House and East Orange, N.J., Paul Hamburg of Adams House and Great Neck, N.Y., and Xavier H. Reyes of Eliot House and Los Angeles.

The fellowship specifications require recipients to live for a year "with a people and culture other than their own."

Miss Young will spend her year in northern India, probably working with native children. Hamburg plans to use his grant to play and study the folk music of the Balkan countries. Reyes will live in an Indian village in the Peruvian highlands.
