joy to Pembroke couple Mr. Hubert Butterfield, 24, and his 25-year-old girlfriend, Miss Renee Arorash. The 5lb 14oz boy arrived at 12.30 a.m yesterday, more than two weeks later than expected. Said Miss Arorash: "He was supposed to be born on December 16. But we're just thrilled.'' The couple have not yet thought of a name for their first child, but are calling him Hubie for now.
