Frank Hansens daugthers, Florence and Hilda

Still I am hoping that someone out there know something abouth my aunts Florence and Hilda. My grandfather Frank Alfons Hansen died in Boston in 1963 and cremated in The Forest Hills. But his wife Anna Andersson did´t burry him then so thats why I can´t find his grave or his daugthers Florence and Hilda. If there is anyone out there that know anything, please help me! Good Bless!
