I am looking for information on the descendents of Ephraim Hiram Baker Knowlton (1786-1867), who emigrated from Ellery, Chatauqua Co., NY to Janesville, Rock Co., WI circa 1840. He settled in Middleton, Dane Co., WI w/ his wife Anna Lepper and son Hiram Baker Knowlton (b. 1810 in NY). I'm hoping someone might know something about his other sons, who also came to Dane Co., WI. Coming at it from another angle, my grandfather Walter E. Knowlton was born 1921 in Chippewa Co., WI. He was the son of Dean Knowlton, born 1888 in Neshkoro, Marquette Co., WI. Dean's father was John B. Knowlton, born 1850 in Janesville, WI. Any help would be greatly appreciated!
