Giacomo (Jimmy) Pellicci, 50, the owner of a barbershop in the Montgomery Mall shopping center, died at Prince George's General Hospital Sunday following a heart attack.

Mr. Pellicci was born in Fiumedinisi, Sicily. He later lived in Milan, Italy, where he became a tailor and a barber.

He came to the United States in 1956 and settled in Hyattsville. He was a tailor at the Garfinckel's department store for about three years.

Then he turned to barbering and worked at the Spring Valley Barber Shop in Washington. About 1966, he opened his own barbershop in the Wheaton Plaza shopping center. A few years later, he added a second store at Montgomery Mall. He continued to operate both businesses until last year, when he sold the Wheaton Plaza store. He continued to work at the Montgomery Mall shop until his death.

Mr. Pellicci was a member of the Roma Lodge of the Sons of Italy, the Knights of Columbus and the parish of St. John Baptist De La Salle Catholic Church in Chillum. He also was a member of the Moose lodge in Adelphi.

Survivors include his wife, A. Lauretta, of Hyattsville; one son, Joseph, also of Hyattsville; three daughters, Graziella and Carmella, both of Hyattsville, and Giovanna Zangwill, of Waldorf; his mother, Giovanna Russo Pellicci, of Hyattsville; and two sisters, Carmela Gugliotta and Maria Ricca, both of Fiumedinisi, Sicily.

The family suggests that expressions of sympathy be in the form of contributions to DeMatha High School in Hyattsville, or to Regina High School in Adelphi.
