As an example, the following obituary
PATERNO O. OBADO (1920-2003) With Peace and Joy, Paterno was joined with our Lord on April 22, 2003. Paterno O. Obado was born on February 12, 1920, in Sarrat, Llocos Norte, Philippine Islands, the third child of the late Elias Obado and Felicissima Balicanpa Obado. From 1943-1946, he proudly served as a sergeant in the Philippine Commonwealth Army, including the recognized guerrillas in the service of the United States Army Forces in the Far East under the Commanding General Douglas MacArthur during World War II.

He is survived by his five children and their families: Franklin and Caridad Aquino of Oakland, Teotimo Constante Obado of Oakland, Apolinar and Kathy Obado of Fremont, Isagani Felipe and Rizalina Obado of Manila, Philippines and, Gerion and Nimfa Obado of Bawang, La Union, Philippines...
The above indicates the Spanish origin of the majority of the christian names in that particular family. (There's nothing to suggest any Celtic connection.)
OBADO IMMIGRATION TO HAWAII - 1950-1959:
OBADO. Vincenta. Felix. Claudia. Honorata. Marcos. Hilario. Fidel. Magdalena. Sulpicio.
And not a single DUPLICATE MAE anywhere that I could find.
In the 59-60 Honolulu Polk there are zero Obado. But those are self-supplied - unlike phone books. In the 60-61 Polk there is a Gloria Obada. No Obado in the 61-62. In the 62-63 there is a Douglas Obada.
I think I have some copies from 61 - 62 phone books, but have to hunt for those.
I know many Filipinos and those types of names are still very commonly used. As well as “regular” English names like “George”. I’ve also seen names like Deli, Desi, Nannette, Edna, Kareen, etc. Haven’t run into a “Mae” but that’s merely anecdotal. When I lived in HI I knew many Filipinos too, and I remember Jaime being a popular name, as well as Spanish derived and funny Filipino ones (funny to me).
