In 1526, in an attempt to establish a Spanish colony, which was the first place in what is now the United States in which a catholic mass was celebrated?

In June 1526, two Dominican priests, Antonio Montesino and Anthony de Cervantes, accompanied several hundred colonists under the leadership of Lucas Vasques de Ayllón from San Domingo and attempted a settlement upon the Atlantic coast of the mainland north of Florida. They first made land at Cape Fear (near present-day Wilmington, North Carolina) but chose to sail on, looking for a more salubrious spot, which they found and established the small settlement of San Miguel de Guandape (or Gualdape) where, during the summer and fall of 1526, they certainly did offer Mass. After the death of Ayllón in October, the colony abandoned the country and returned to San Domingo.
