Judith Lynn Shaffer was born 1945 and living in Vancouver in 1991, so it's possible she is still living today. You may want to narrow your search for her by specifying only Canadian records.
William Henry Smith II born 1932 will be a more difficult search because it is such a common name. If you can track down an obituary for Norma it may give you some leads to finding her siblings, William and Judith.
