My father was born in 1919. Although he changed his last name during the war, he kept his first name of Paul. I don't recall anyone in my father's family called Hedwig, but it is possible there might be a relation.
Pete, thanks very much for the information on the Army Service Record. That is great news. I am very curious to see the information on our father contained in his service records. I am also hoping there will be some information in the records that might help us locate our half sister.
Thanks again for everyone's help in this forum. It is deeply appreciated!
The following is a picture of our father (on the left) in Germany with his girlfriend at the time and our half-sister. We are not sure when this photo was taken.
I am uploading this just in case there is anyone out there who might recognize anyone in this photo.
