"Reunion of 'tenth-born children' sets Guiness Book world record in Argentina"

Now here's a cool idea:

Forty one people who are the “tenth-born” child in their family met in Buenos Aires in July to honor St. Gianna Beretta Molla, establishing a Catholic “Guinness” world record.

Promoted by the Argentinean Catholic daily, “Cristo Hoy,” which has one of the largest circulations in Latin America, the event attracted the attention of the press because of its message of love for the family and life conveyed by those who attended the gathering. (CNA)

I wonder if American Catholics could hold an event to challenge it.
