I've postulated this answer before. Stanly Ann was irresponsible. Anyone so irresponsible as to HAVE their child in Canada, (and therefore depriving him of his highly valuable American citizenship) is likely too irresponsible or lazy to have gone to the trouble of registering him in Washington. (assuming you could get witnesses to go along with it. People generally had more integrity back then.)
Madelyn, on the other hand, was the epitome of a no nonsense doer. She didn't mess around, she took care of problems for her irresponsible daughter. (note that Barry lived with Madelyn rather than Stanley Ann from 1971 onward. )
Besides, Hawaii's birth certificate laws were probably the laxest in the nation,(and still are) and Madelyn also did work at the local courthouse and was likely above question or reproach.
It was EASY for Madelyn, and perhaps not so much for Stanley.
Did MD do work at the local courthouse in 1961? IIRC that was later.
And why send SD to Canada to have the baby?
Why not send her to the Booth Home in Honolulu or Spokane?
Do you think SD could have paid her own plane fair to Washington? Obviously MD was running the show.
BTW, here is the Pennsylvania law (VITAL STATISTICS LAW OF 1953) on registering births (amended in 2001):
“Section 401. Birth Registration: General Provisions.—(a) A
certificate of each birth occurring in this Commonwealth shall be filed with the local registrar of the district in which the birth occurs within a period prescribed by regulations of the Advisory Health Board. The certificate shall be prepared, signed and filed by the attending physician or licensed midwife, except that when there is no attending physician or licensed midwife the certificate shall be prepared, signed and filed (1) by the father, or (2) in the event of his death, disability or absence,
by the mother, or (3) in the event of her death or disability, by the householder of the premises or superintendent of the institution in which the birth occurs, or (4) in the event of the absence or disability of all persons heretofore named, then by such person acquainted with the facts as the local registrar
shall designate. The Social Security number or numbers of each parent shall be obtained and maintained separately by the department in a fashion that permits routine screened inquiries, unless there is good cause for not requiring the furnishing of such number or numbers in accordance with Federal regulations. This information is considered confidential and is to be made available only to Federal and State agencies responsible for establishing paternity or enforcing child support orders.
(b) Upon filing of the certificate, the department shall
provide the father or the mother with a brochure relating to
the existence of and eligibility for the Children’s Health
Insurance Program (CHIP) under Article XXIII of the act of May 17, 1921 (P.L.682, No.284), known as “The Insurance Company Law of 1921.”
(401 amended June 25, 2001, P.L.725, No.69)
Looks like just about anybody can register a birth in Pennsylvania.
