An issue of great concern for my colleagues at the Canadian Council of Natural Mothers CCNM is that when mothers relinquished, and gave the father's name, wrote it in on the forms for the birth certificate - it was deleted, whited out, expunged.
Now that the records have been opened, adoptees are finding their mother sbut not fathers.
Karen Lynn of CCNM says they went to great extent with photo copying secions of the forms that were whited out so that the dotted line she KNOWS she wrot eon appears to be in tact!
Apparently, the law, up until 1986, forbade listing the father's name on birth registries or adoption papers for children of unmarried mothers unless both mother and father demanded it. So only some 10% of those documents identify a father.
