Sorry, When I typed Bertha, I must have been having a very senior moment, I meant Laura Clinkard.
Regarding the entry for Border Crossings: From Canada to U.S., 1895-1956
The date of 1955 is not correct. I have now looked again at the handwritten copy, and what is says is 4/14/1938 and immediately after that is says SS Britannia.
So it looks as if she crossed from Canada to the US, and then came back to England from the US, which makes more sense, as she was 60 years at the time.
I am sending you a message on the contact line, which will give me own email address. Contact me direct and I will try to send you copies of what I have.
