Hi Herb,
You gotta read all the form very carefully, maybe 3 or more times, as they jump back and forth between the applicant and the spouse.
Maria, the wife, said about her husband is in the blue area. After that, it goes back to Maria, in the pinkish color:
So yes, Maria states that Mariano was born 12 Jan 1881 in S. MIGUEL. Nothing outside of the island is stated for him for a birth place. His immigration date is stated. If you can find him on American arrival end, you should be able to find him emigrating out on the Azores end.
You are so focused on Mariano that you didn't let your brain click back over to the wife Maria, and when you saw that she immigrated from Ponta Delgada, you let your brain take the ball and run, but kinda in the wrong direction (LOL).
You can ask the church where they got married to look at their marriage book and see if it stated where they were born.
You can order the Alien Registration on Mariano, if he was not a U.S. citizen by 1940.
You can go to Estrella and see if his baptism is there on or around that date.
Good luck,
