Georgetown was a community south of Middletown at the present site of Oxford State Road and Yankee Road, and part of the unincorporated suburb of Oneida in Lemon Township. There also was a Georgetown south of Fairfield Township in Colerain Township in Hamilton County. Ruth J. Wells in her book, Colerain Township Revisited, said "Georgetown (Dunlap) was laid out in 1829 at the junction of [old] Colerain Pike with Kemper Road. The post office was established in 1837 with David Wallace as postmaster." Some sources indicate it was on the line dividing Butler and Hamilton counties, and possibly partially in Butler County. It was a mile and a half south of the Butler County line, Mrs. Wells explained. "The George Struble farm lay east of Colerain Pike and it is said that the village (Georgetown) was named for him," she wrote. "John Dunlap is said to have been the first postmaster in old Colerain. The PO continued to bear his name and was located in the old Cotton mill down by the Great Miami River. When it was moved it carried the name, Dunlap, to the village on the hill." Today, the community that started as Georgetown is identified as Dunlap by signs along old U. S. 27. This Dunlap is not the same as Dunlap Station, or Fort Coleraine, established in 1790 by John Dunlap. Of the founder, Mrs. Wells said "he was one of (John Cleves) Symmes' surveyors and a native of Coleraine, Ireland." She also said "all trace of the first village of Coleraine disappeared. It was situated on the great bend of the Miami several miles below the bridge to Ross. A second Colerain, or Coleraine, was started just above the (Venice) Ross bridge," near the Butler County line. "In 1819," she wrote, "David Stone of New Hampshire built a cotton mill at Colerain where Toad Creek enters the Great Miami (River Road, just east of its intersection with Colerain Pike). In 1821 this was sold to Giles Richards and Timothy Goodman. A grist mill and saw mill were built. A tavern and dye house were added. A thriving town grew up here. The cotton mill later became Matson's Woolen Mill. This village had virtually vanished by 1875 and nothing remains to mark its location today," Mrs. Wells noted.
"The last surviving remnant" -- the woolen mill -- "was washed away and destroyed by the 1913 flood." She also added that the second Colerain near the Butler County line also was known "as Cliptown from the clips of wool" associated with Matson's Woolen Mill. Colerain Township -- which borders on Fairfield and Ross Township -- was created in 1794, nine years before Ohio became the 17th state and the formation of Butler County from Hamilton County.
