Need some help in positively identifying a Canadian airman.

On 26-6-1942, 1 OADU Hudson IIIA FH230, crashed and was destroyed by fire when an engine cut on approach to Luqa, Malta.

I have the following crew:

R/81436 Sgt (Pilot) E J DOHERTY/DOCHERTY RCAF - Survived
1064002 Sgt (Obs.) Stephen MATTHEWS RAFVR +
1260278 Sgt (W.Op./Air Gnr.) Wilfred John CULBERT RAFVR +
AUS407650 Sgt (W.Op./Air Gnr.) Maxwell Ernest REDDEN RAAF - Injured

Can anyone positively identify, DOHERTY/DOCHERTY?
