I find mention of one Kerns in the Fillmore County book.
Francena Kerns is shown as having a plot of land on the Geneva Township Homestead map. No other mention is made of the surname Kerns.
There are two mentions of the surname Lightbody in the book. On the Stanton Township Homestead Map, both Isaac Lightbody and James J. Lightbody are listed has having owned plots.Also in the book is a 2 paragraph entry for J.J. Lightbody. Since it is so short, I will copy it here.
"J.J. Lightbody was born on January 3, 1849, at Plainfield, Coshocton County, Ohio. After marrying Lovina M. Saylor on July 29, 1869, he moved in 1869 to Iowa, where they lived for a year. In 1871, they homesteaded on Sec. 1 Momence township, and had a piece of land across the road in Stanton township. At first they lived in a sod house in Stanton, while he built a frame house in Momence, to which they later moved. They had five children: Lizzie, Annie, Charles, Isaac, and a girl who died in infancy. By hard work and by such sacrifices as those of many other pioneers, he accumulated a substantial amount of property and at the time of his death (April 12, 1874) was one of the largest landholders in Fillmore County. He truly saw the whole change from barren prairies to fertile fields dotted with villages and cities. Besides his extensive farming operations, he built several homes and brick buildings in the west side of Geneva. He was always generous and kind, as well as keen and alert and ready to assist in any way toward the betterment of his community and his town."
There is also a picture of the J.J. Lightbody family. The caption says it was taken sometime before 1891, is was provided by Mrs. Sylvia Stoldorf.
If you would like a copy of this entry, I can scan it for you and email it. Let me know.
