My grandparent's names are Rose,Jeanette,Peter and Luis but I don't consider them to be old fashion. To tell you the truth, neither do my great granparent's names - Anne, Mary Ellen, Alexander, Charles, Sebastiano (Sebastian). (my one ggrandmother's name has completely slipped my mind right now)
When I think old, I think
Ida
Sally
Gertrude
Edith
etc.
Harold
Gerald
Eugene
Theodore
etc.
