Speaking of the family of Lt. Mike Haines.....
I think it's pozz'ble, just pozz'ble (as Muskie Muskrat would say) that the 'N.Y.P.D.' detective had an older brother who served in the Navy during World War II, first in the Pacific and then in the Mediterranean. His first name was Joseph, but everybody knew him as "Happy". He was a crew member on board the PT 73, whose crew was known as 'McHale's Navy'.
Whether he had ever been a red-head like his younger brother, it'd be impozz'ble, just impozz'ble to say - since he lost most of his hair at an early age and what was left had turned dark (as happened with my Dad and my sister.....)
