This doesn’t quite fit your discussion of dual citizenship, but I found it interesting.
Theodore Roosevelt’s “Fear God and take your own part”
Chapter 9 “WHEN IS AN AMERICAN NOT AN AMERICAN?” on page 284 begins his discussion on dual citizenship.
At the end of this chapter, he writes,
“President Andrew Jackson on this theory could have been impressed for military service in the English army against which he fought at New Orleans, if he had ever happened to visit England; and President Arthur would have been in the same plight.”
I’m not sure why he mentions President Jackson as having a dual citizenhip, President Arthur is obvious.
“President Andrew Jackson on this theory could have been impressed for military service in the English army against which he fought at New Orleans, if he had ever happened to visit England; and President Arthur would have been in the same plight.”
Hmmm....
This quote from Teddy Roosevelt show that at least TR had concluded that Pres. Arthur was a UK subject and dual citizen at birth. Was TR basing this on suspicion that Arthur was born in Canada, or knowledge that Arthur’s father did not naturalize as a US citizen until after Arthur was born?
Leo Donofrio made quite a bit deal over how he and his sister “discovered” the naturalization papers of Arthur’s dad.
