"In November, 1855, in company with his brothers, he . . . made claim to a tract of land and settled the town of Mantorville, county seat of Dodge county. Here he built the first saw-mill and the first grist-mill on the Zambro River. In the winter of 1856 Mr. Mantor visited Washington, and secured the establishment of a large number of postoffices and post roads in the territory; he also aided in securing the passage of a bill for the relief of settlers in the territory; during the same time he was largely engaged in mercantile business. In 1857 he was elected delegate to the Constitutional convention, which met to prepare for the admission of the territory into the Union. At the first Republican State convention, receiving the unanimous nomination for State Treasurer, he jumped the State, but, with the entire ticket, was defeated." (Obituary, Hon. Frank Mantor, The Linesville Herald, date unknown.)
Mr. Mantor retruned to Conneautville in 1860 and was involved in the political and commercial life of Pennsylvania until his death. (Obituary, Hon. Frank Mantor, The Linesville Herald, date unknown.)
"[The name of Mantorville] was adopted in honor of three brothers, Peter, Riley, and Frank Mantor who came here in 1853 and 1854 from Linesville, Crawford County, Pa." (Minnesota Place Names, MHS, 2001)
