I have the same blood type as my father, but one of my brothers had the same principal type as my mother, but the opposite Rh-factor.

Blood type has nothing to do with personality.
 
FWIW - there a lot of blood groups beside the A,B,O antigens and the Rh factor antigen.

And. If there were an effect outside of the immune system (I know of none) the effect would be due to the fact that the locus (parking place on the chromosome) for the ABO group lay really close to the locus for some personality gene.

Based on what we know about epigenetics, I'd say look there first.
