San Lorenzo, Puerto Rico Genealogy

Guide to Municipality of San Lorenzo family history and genealogy: birth records, marriage records, death records, census records, and military records.

History
San Lorenzo was founded in 1737 under the name San Miguel de Hato Grande by Valeriano Muñoz de Oneca from Seville, Spain.

The exact date is not certain because the parochial archives of this municipality were lost in a fire and no copies were available.

The original settlers of the then-village were the Muñoz de Oneca, López de Alicea, and Sánchez de Cos families. The church was erected in 1811.

Hurricane Maria on September 20, 2017, triggered numerous landslides in San Lorenzo with a significant amount of rainfall.
