Kevin,
I checked on Jennifer Glauvitch, but couldn't find any info. Same for Heidi. Are you sure about the spelling of the last name?
I found info on Emmi (Emilie) Vogel ... does any name in this obituary seem familiar?

I wonder why "german mother" is in parenthesis... And Mainzlar is only app 12kms from Giessen...
You can send me an email to

Greetings from Germany
