xbox live transfer

Current situation....

• 2 Xbox One's in same house
• Father doesn't play xbox but has xbox live associated with his account
• Set father account as home on child 1's xbox - live works fine
• Cannot set two xbox's as home so child 2 doesn't have live.

Is there anyway to get xbox live on child 2 xbox without buying another subscription?

I was thinking that I could cancel father account since he doesn't use it then just have child 1 as master to share it to child 2's xbox.

Also, I can't find a way to move the xbox live subscription from one account to another so I can cancel the father account

Appreciate any information on this.

My son and my nephew have their account in my X1, both can play on-line and mine is the main account.

@raugutcon: I think that is because it's on the same xbox? My situation has two different xbox's.
