From the Handbook of Texas Online:
JOPPA, TEXAS. Joppa, on Farm Road 210 and the North Fork of
the San Gabriel River, seven miles northeast of Bertram in Burnet
County, was first called Pool Branch, after a nearby pool formed by
a waterfall. At that pool in the 1880s were a cotton gin and a
mill; just southeast of the gin were a store and a blacksmith shop.
On August 31, 1881, J. S. and Jane Danford of Delaware County,
Iowa, gave two acres of land on the north bank of the North Gabriel
to be held in trust for a school and a church. The school building
was constructed at once and used for classes and church services.
Worship was held in the schoolhouse until 1913, when a church
building was erected. The local school, the church, and the
locality were called Pool Branch until 1891, when the community
secured a post office, and the people agreed on the Biblical name
Joppa. On May 19, 1904, a telephone line was installed in Joppa. An
iron bridge was built across the San Gabriel River in 1907 and was
still in use in 1989. The area received electricity in 1939 from
the Pedernales Electric Cooperative.qv The school was consolidated
with the Bertram district in 1942. Friday and Saturday night
socials and Sunday night singings culminated in an annual picnic as
late as the 1930s. The church and school buildings were still used
in the 1980s for church and community activities. In 2000 the
population was thirty-four.
