Thine Thoraldson was the name of Harry Thoraldson's mother. Ole Thoraldson was the name of Henry Thoraldson's father. Thine was listed as Harry's emergency contact in his file, the letters concerning his death were sent to Ole.

The fullest version of Harry Thoraldon's name I could find is 'Harold M. Thoraldson'. (I could find no record of what the 'M' stands for.)  He was unmarried.
