I have a great Aunt that was born in Canada 1909 (during summer work) so I always thought she would be Canadian. They were from Seattle and all other children were born in the States and both parents were US citizens. In the 1920 census I found the family still in Seattle with this child age 10 / born Canada with parenthesis at the end of the line that said (BORN AMERICAN CITIZEN). It might help to find other census years to get her age and place of birth. Washington and Oregon are very easy to find birth information. Star
