He was making great progress in his work, expecting to complete and return home in about a year. On the day of the sad occurrence the family were celebrating the eighth birthday of little son, Bennie GOULD, and also the high Sunday holiday of the Spanish Catholics by a picnic at the request of the faithful attendant who had been the boy's nurse, almost from the day of his birth. ...

The faithful girl was buried in her own consecrated ground with the rites of her own church. Her named was Alvina FONTAINE. She belonged to Digby, N.S. and was 25 years of age. - 'Boston Journal' (see original)
