Can you tell me where your father fit in with his siblings as to ages.
Also, where were all the children born?
I am wondering where they would have been before 1930's
Where were Adam an Julia born?
You said they were in Demaine area about 1930-1935 - do you know where they went after that?
If you have some approximate birth years and places it may help to find them - especially Adam and Julia who may show up in census if they were in Canada early enough - were they born Canada or elsewhere ?
