That is a 1940 census record. That Peter fits the description you gave - you gave no date of birth. Clearly now that you have added information, we can see he's not your Peter.
My thought was to help you begin in the USA to find Peter and trace him back in time. But you have already done that - as we can now see. Bravo! Sadly, I cannot help with the rest of the task, to look up the birth record. I hope you can find that.
