Also note (and it’s small, but who gets their age wrong in their 20s?) that the birth cert says BHO Sr was 25 in August 1961, but this says he would have been 27.
on arrival in the US his birthdate is shown as 1934, he signed the above in September 1962.
Then it changes to 1936, but without going back through the entire file, I do not know or recall just when that change of year took place.
The 'certification of live birth' COLB shows him as being aged 25 in 1961. So he is 25 years old in 1959, and 25 years old in 1961.
And when he was buried, the year is once again 1936.
