Henry W. is my great grandfather's brother (John L.). I have lots of general info on the Kestner family from Adams County, Illinois. Their father, Frank W. (Franz Wilhelm) came over in 1858 with his fiance or maybe they were already married, and settled in Adams County, Illinois around 1860.
Henry W. married Amelia Hanke on 2/17/1883 in Adams County, marriage cert. #2563. He had 3 sisters, Emma, Frederike, and Elizabeth. Email me at firstname.lastname@example.org if you want some more info.
