I requested a copy of John Luka's social security record (thinking he was my grandfather's brother) and to my knowledge he is no relation. The information on the record is as follows:
John Daniel Luka
b. 11/17/1901 - Chicago, IL
ss# 357-03-3007
Father: Joseph Luka
Mother: Francis Zboralska
If he could be related to you and you would like a copy of the social security record, please contact me and I would be more than happy to email you a copy.
