When Hawaii was being considered for statehood, there was a minimum population requirement (600K, as I recall).
Hawaii fell short of that total. But, in order, to create more population they passed what was called Territorial Law #57
It authorized the DOH to accept as Hawaiian-born citizens children who were actually born elsewhere.
This law was still in effect in 1961, after Hawaii became a state.
Thanks. That is very interesting. It definitely fills some missing pieces.
