Your information appears to be in error. My copy of the CRC Handbook of 
Chemistry and Physics (61st Edition) gives the following boiling points:

Methanol:    65
Ethanol:     78.5
1-Propanol:  97.5

It does indeed go as molecular mass, as long as there is only one alcohol 
group; compare 1-butanol (b.p. 117) and ethylene glycol (b.p. 198).
