Hello,
I found a Gloria Goodwin (husband: Samuel).
Address:
85605 Yates Blvd.
Chicago, IL 60617-2316
Telephone:
773 375-3418
I found listings for the name Mock in Chicago, but not Elsie. Does she have a husband? What is his name?
I hope this information is of help in your search for your cousins. Please, let me know if I can help you further.
