I have the following information from a YiskorBook in Lithuania.
Rabbi Yosef Katz had 2 sons in laws , Abramchik Yossel and Itzik Yossel.
Now Abram(chik) was my great grandfather. He definitely did not have another name Yossel .His father was not Yossel.
I am wondering whether the Yossel in both sons in laws' names actually refers to their father in law Yossel.
Is this a known name usage ?
