How many different countries were your great grandparents born in?

[Mr. Morden]

How many different countries were your great grandparents born in?  For simplicity, use modern international borders to define different countries, so as not to have to pull out pre-WWI maps.  (Though I guess many of the young folks here wouldn’t have great grandparents born before WWI.)  Or if you really want to use international borders as they existed at the time, fine.  Go ahead.  I leave it up to you decide how to count the constituent pieces of the UK.

For me it’s 5:

3 born in Canada (all in Ontario)
2 born in the US (one in Chicago and one in Milwaukee)
1 born in the UK (in Cornwall, England)
1 born in Germany (in Westphalia)
1 born in Norway

[Mr. Morden]

All in the US. The most recent immigrant was one of my great grandfathers who moved to Brooklyn from Montreal in the early 1870's.

Am I missing something here?  The question was how many countries were your great grandparents born in.  You said that yours were all born in the US, but then in the next sentence said that one of them immigrated to the US from Montreal.  If one of your great grandparents was an immigrant to the US from Canada, then wasn't he born outside the US?

I missed the word "great." So the erratum has been corrected. Thank you.

Ah, no problem.  Btw, I just recently found out that (assuming records are correct) one of the Canadian branches of my family tree has a sub-branch that extends back to the Dutch settlement of New Amsterdam.  So the earliest direct ancestor of mine to be born in North America was born some time between 1640 and 1642 in what's now NYC, and she lived most of her life in whatever the settlement was that's now Kingston, just down the river from you in Hudson.  While she was born around 1640, I don't know what years the respective families of her parents immigrated from Europe, so I can't say whether I can match your 1637 date or not.
