I am sorry to read that you lost your father...he sounded like quite a guy from what you told me in the past--you must miss him.
I just found Marion (Dolly) McDaid in the 1937 Fitchburg High School Yearbook, "The Boulder." Here is the text on her:
Fitchburg High School
CLASS OF 1937
Marion Margaret McDaid
She's fair whose beauty makes her gay.
Dolly, though born in the jungles of Panama, has no savagery
in her conduct. Rather to the contrary, refinement and sincerity
characterize her. Perhaps we may attribute to her sparkling eyes,
the train of broken youthful hearts she has left in her wake.
