I am researching for someone else and they asked me to check into these two names for information. The names are John Vocelka who lived at 410 N. Hermitage Abe. In Chicago,Ill. in 1913 and one Karl Worle who sent this John Vocelka a package in Oct. of 1913. Karl lived (address found on clock package mailed to John) Heidelberg Rahzbachezst. 45 Germany. Any help as to how to research this would be appreciated. Thanks in advance
