Have you been to the Mormon Family Search site? https://www.familysearch.org/
If you put in just the last name LASPONIA, you'll see Pedro, Anastacia, Florencia, Joe, Flora, Hipolita, Fausta, etc.
Some info comes from Census Reports, so will have relatives included if they lived in the same home.
Also will find the Social Security Numbers. Send away for original Social Security Number application because it will have their parents names. You can purchase them from the SS site.
ALSO will see Hawaii wedding information, with great info
groom's name: Pedro Lasponia groom's birth date: 1896 groom's birthplace: groom's age: 23 bride's name: Flora Furtado Rapose bride's birth date: 1903 bride's birthplace: bride's age: 16 marriage date: 07 Aug 1919 marriage place: Lahaina, Maui, Hawaii groom's father's name: Eusebio Lasponia groom's mother's name: Juliana Mazalton bride's father's name: Jaeintho Furtado Rapose bride's mother's name: Maria Augusta De Medeiros
Once you have the parents names, then you can just follow the trials by their last names.I recommend just putting in last names until you get a feel for the region where you might narrow your search on the Mormon site.
Good Luck to you!
