Lowrey is of Scottish origin, with two potential meanings. The first could be a patronymic surname meaning "son of Lawrence;" the second being based on the Scottish word lowrie meaning "foxy," having the crafty look of a fox. It can be traced back to the late 1600's in Dumfriesshire, Scotland.

From DeKalb County's "Landmarks of DeKalb County" webpage:
Salem Methodist Church was organized around the mid 1850’s. In 1876, G.W. and Jane Black deeded two acres of land to William A. Elrod, A.N. Lowrey, William Nunn and Nelson Elrod for the purpose of building a school house and a house of worship for members of the Methodist Episcopal Church South. Phillip Elrod, who helped establish the church, preached the first sermon and was the first person buried in the cemetery. The first pastor of record was Aaron Newton Lowrey.

From "Who Was Who in DeKalb County" by Elizabeth S. Howard, page 101:
[Aaron Newton] Lowrey moved to DeKalb County some time between 1850-1860. He settled at first in the valley, but soon moved to Sand Mountain to the Oak Hill Community, near Geraldine. He homesteaded 160 acres of ection 20 in township 8 of range 6 east. There were no real roads on the mountain at that time and cotton had to be hauled by ox wagons to Gadsden to the nearest gin. The Reverend Mr. Lowrey helped to build a road when the dirst and rocks for the big fills had to be hauled with wheelbarrows. He was a farmer and also a Methodist circuit rider, traveling by horseback over his circuit, which reached all the way from Langston, in the Tennessee Valley, to McCauley's Chapel, near Noccalula Falls in Gadsden. He was the first pastor on record at the Salem Methodist Church at Geraldine and also served Lusk Chapel, Jones Chapel, Bethel, and Chestnut Grove. His name appears on the 1866 report of DeKalb Lodge 116 of the Masonic Order. He became affiliated with the Van Vuren Lodge No. 355 on May 13, 1870, and remained a member until his death.
