At the request of the Rev. Dr. J. Carroll . . . Doctor of
Divinity, superior of the Roman Catholic Clergy . . . John Threlkeld
doth grant unto the said John Carroll . . . Lot Number seventy-two
. . . for the purpose of erecting and maintaining a Chapple or
house of worship” (Deed of Conveyance, April 24, 1787).
Thus John Threlkeld, an Anglican and second generation Marylander,
and Dr. Carroll, eventually consecrated as the first American
Catholic bishop, laid the foundation for a system of churches
throughout Maryland and Virginia. In 1792, Dr. Carroll appointed
Father Francis Ignatius Neale, S.J. and the founding pastor
of Holy Trinity, to commission the first Catholic house of
worship in Washington. Records substantiate the church’s
completion circa 1794.
The parish originally served not only the growing Catholic
population of Georgetown and the students of the College, but
the entire area that now constitutes metropolitan Washington,
DC. The building was beautifully sited on a high embankment
overlooking “N” Street. Before the construction
of modern buildings nearby, its steeple could be seen from
most points of the busy Georgetown riverbank.
As the congregation grew, so did the needs of the Parish. By the mid-eighteenth century it was necessary to build and
consecrate the “new” church where we worship today. The original church building was doubled in length in 1870
to serve as the parish school after the “new” church
was built in 1851. It also served as the parish convent after
two new school buildings were built in 1918 and was used as
the Parish Center, a hub of myriad parish activities, from
1986 to 1999.
