It's interesting that the FIRST Roman Catholic settlement in what became the USA is omitted, that is St. Augustine Florida.

St. Augustine was established in 1565 by Spanish adventurer Pedro Menéndez de Avilés, when he had summarily executed several hundred French Calvinist prisoners he captured by taking over Fort Caroline, in what is now Jacksonville, Florida--murdered by Menéndez expressly because they refused to convert to Roman Catholicism.

Fort Caroline--the first European settlement in what is now the USA--had been established for Protestant refugees fleeing the serious butchery occurring against them by Roman Catholic authorities there too. In 1572, for example, in France in just a few days time, over 10,000 (yes, ten-thousand) French Calvinist civilians were murdered just because of their faith.

There are very good factual historical reasons why America's Founders were suspicious of the Roman Catholicism of their day.

Where was the first Catholic Church built in America? And what was the name?

The first Christian worship service held in the current United States in 1559 was a Catholic Mass celebrated in Pensacola, Florida. (St. Michael records)

The first Catholic settlement in North America was the Spanish-Catholic colony founded at St. Augustine, Florida, in 1565.

Saint Augustine Florida is the oldest European city in the United States. The city was founded by Pedro Menéndez de Avilés on September 8, 1565. Martin Francisco Lopez de Mendoza Grajales became first parish priest of St. Augustine, the first established parish in the United States. Its church records, dating from 1594, are preserved in the archives of the present cathedral.

St. Ignatius was founded in 1641 by Jesuits who arrived on the Ark and the Dove to assist in the forming of a new English Colony. St. Ignatius is located in Port Tobacco, Maryland on Chapel Point road. It remains the oldest continuously serving Catholic Church in the United States.

your numbers are off. Now wikipedia's not the ideal site, but your number of ummarily executed several hundred French is quite wrong -- the real numbers are bad, but not that bad: "The Spanish easily overwhelmed the lightly defended French garrison, which had been left with only a skeleton crew of 20 soldiers and about 100 others, killing most of the men and sparing about 60 women and children."

The original garrison was about 200 people INCLUDING the women and children, so your number of 100s is false

secondly, this was war, not a massacre. The ones fighting were armed and fought against another colonial power.
