While researching my Trease ancestors, who were living in Jasper Co., IA (Kellogg area), I found that 2 of my great grandfather Lewis Jefferson Trease's sisters married SHILL boys. Emilia Jane Trease married Jacob F. Shill in 1866, and Lucy Ann Trease married David Shill (no date for marriage.) In the 1880 census for Jasper Co., IA, David and Lucy Shill are both listed as age 38. I have David and Jacob both as being born in OH (Jacob as Montgomery Co.)I have nothing yet on their father or mother. Looks like some of us might have a link, so would sure be willing to exchange information.
