Prior to July 5, 1975, the birth record of an illegitimate child showed:
Only the name(s) of the parent(s) registering the birth, and
Only unmarried persons as the parent(s).
Thus, for example, a child born to a married mother and a single father had to be
registered by the father; the mother's name could not be shown. If the married parent
was later divorced or widowed, his/her name could then be added to the record.
