Thanks for the Dresden Clue garstonite, and thanks aghadowey for the look up.
Unfortunately, he arrived in the USA as a German POW and the authorities there (and in Germany) no longer have a record of him or his service number.
After the war he was repatriated from the USA but for some reason opted not to return to the Eastern sector!!!!
As for 1959-1960, I am able to remember both events having personally attended that English wedding as best man and do have a copy of that certificate.
I had hoped that as I knew his parents' names and dates of birth, I would be able to circumnavigate him and start building from them. But as you point out, many 19th century German ancestral resources are not accessible via the Internet, and a Germanic family history society would require a location, so accessing anything without more details would be a problem. Never mind, it was certainly worth asking and I much appreciate your advice and thoughts on the matter.
