In addition, I've noted that Geni's programing now often only gives you the option of locations in terms of today's geography.

I have this same problem with my English ancestors who immigrated to the US. The BIgelow family progenitor arrived in 1630 with the Winthrop fleet . He was born 1616 in England, died 1717 in the Province of Massachusetts, he never did live in the United States of America (USA), which itself was not born until July 4, 1776.
I think we should be historically accurate, and allow those who become perplexed and have the initiative to Goggle it.
