Q. What is our father's name, or rather our family name? Who is he?
The more of our (first) names you unlock, the closer you are to finding out my father's name. After all, we are all related somehow!
We'll briefly introduce ourselves, then.
Hi, I'm his 1st son:
I blew up in anger when my friend said I stank, then I decided to vanish into thin air, not to be found again.
Hi, I'm his 2nd son:
I am invisible here but built a :y
Hi, I'm his 3rd son:
Fine and dandy to work so hard at the gym, but you guys need to take off your sweaty ING before getting on me on your way home.
Hi, I'm his 4th son:
People need me and consume me, greedy ones seek and crave for me, but I may not, I might, I might.
Hi, I'm his 1st daughter:
Just 'cause I look damn hot, don't you dare touch me! And don't even think about asking me out on a rainy day, 'cause I won't look good anymore... Not at all...
Hi, I'm his 2nd daughter:
Be sure to drop in on me and use me when you are nearby. Don't just dump your better half on the street, ok? I'll be looking at her every move, or rather non-move, until you leave me.
Your last name is
1st son is
GAS (STATION) (@QuantumTwinkie)
2nd son is
SPACE (STATION) (wolfram42)
3rd son is
TRAIN (STATION) (training at the gym, get on the train home)
4th son is
POWER (STATION) (wolfram42)
1st daughter is
FIRE (STATION) (QuantumTwinkie)
2nd Daughter is
PARKING (STATION) (wolfram42)
2nd son seems to be
Space. The invisible characters are spaces, :y = colon y = colony. A space colony.
3rd son is
Train, thanks Pierre Cathé
4th son seems to be
Power. It is consumed (electricity), craved by the greedy, a synonym for might.
Second daughter might be
Parking. Your car is your better half. Leaving your car at a parking station will have it under surveillance (and it won't move). It is also better than dumping your car on the street.
Last name is probably
Station since it follows all of the words found. The "Seventies" clue is that there is 7 letters.
