I simply provided you with an example ~ millions of Americans today have an ancestor who was a White Coat in the French army that lost to the Brits in Canada in the mid 1700s.
They don't even know those people existed ~ we are THEIR FUTURE.
Those fellows are hard to find in anyone's genealogy, but probability says they really are there but you have to look for them.
I hope you can figure it out from there ~
Yes, the nation we have and know, not a military unit, or the last member of a family, or an expeditionary force.
