Tim, Sheila McCarthy, Nancy Gowans holding Denis McCarthy , Collins baby & Boy

I expect it was in Police living quarters veranda in Kowloon. 
Unfortunately, I don’t know the baby or boys first name but believe them to be the children of Collins a police officer who was from Cork. 
Nancy Gowans was the mother of Jo Jo  who appears in another photo with baby Denis McCarthy. Nancy is incorrectly named as Jo Jo on this photo. 

Date picture taken
1947 (year is approximate)
