Could be the power resides within Elsa's family are like;

First-borns acquires the bulkhead amount of power as an active force, the later ones still acquire the power genetically but theirs lie dormant. And whichever one have children still repeats the process.

Think if Anna have children HER first-born would still be acquiring this power as an active force, and her second(if any) would again be dormant.

Also, I don't think Elsa's power was a curse - it's more like the forces of Mother Nature at her command. Bunch of ambiguous rocks instilled stupid ideas to her parents causing the following story; with right people to guide and train her, think this could be something to be awed than feared.
