I grew up with Michael, Janet and Alfred Liska. They lived on Centennial Avenue in Cranford, New Jersey in the 60's and 70's. I think that their dad was also a Michael. I have lost touch with all of them. I believe their dad Michael came over from the old country(wherever that was).
Michael was born about 1944 Janet about 1946 and Alfred 1950.
Sorry I am not more help.
