These are the passages that mention it, exactly as the scans read.
HIS township lies in"the southeast corner of the county, with Kendall County on the east, La Salle on the south, Squaw Grove Township on the north, and Victor on the west. It has a good supply of timber along the banks of Somanauk Creek, with which it is well watered. The Chicago, Burlington & Quincy Railroad passes through the southern portion of the township, through the city of Sandwich and village of Somonauk.
The first permanent settler of the township was Reuben Root, who first located on section 35, the place now owned by David V. Kinney. He sold this claim to Mr. Davis in the summer of 1835, and moved a little farther north, occupying a house which some years after became the property of Mr. Beveridge, and which it is said was erected some time in 1834, and occupied in the winter of 1834-5, by a Mr. Robinson. The exact date of Mr. Root's settlement is not known, but supposed to be in February, 1835. He was living on the Davis place when William Poplin arrived in March, 1835. Reuben Root was a native of New York. For some years he kept a tavern and was the first postmaster of Somonauk. Selling his claim here, he moved west and has since died.
Willliam Poplin was doubtless the second to locate on Somonauk Creek, in this township. He arrived here, as stated, in March, 1835, made a claim, erected his cabin, and made other improvements the same year. His selection was a wise one, and with his " good wife " he yet resides upon the old homestead, where they have spent a full 50 years.
Machine-read from a century-old scan, so expect the errors a machine makes: misspelled names, dropped words, stray characters.
