Hi John,
I do not have any info to help - the info you posted does not look familiar - but I am a Kaelin from Philadelphia. My Great-grandfather Joseph Martin Kaelin came to Philadelphia from Einsiedeln, Switzerland in 1889. His son, Martin Joseph is my grandfather.
My grandfather left his wife sometime in the 1930s and started another family with a woman named Mary Burke, they had two children (that I know of), however, I do not know their names.
If this sounds familiar or if I can help, just email me. I am the Listowner fro the KAELIN-L and I have a website called The Kaelin Ancestry Page:

Hope this helps.
