I am also interested in Jager/Yager/Yeager families of NY. My gg-grandfather was George W. Yager/Yeager. He was born in Harrisburg, Dauphin Co Pa., abt 1829-30. He turned up in Preble Co Oh in 1849 alone, working as a cabinet maker. He was 19 years old. He later ended up in Daviess Co Indiana where he raised a family of four boys and three girls. Census info lists his father as born in NY, his mother born in England. His birth/death info lost in courthouse fire. He worked for the railroads while in Indiana, they did not keep any personel info on employees. Any help or possible connection? There was a Henry Yager at his funeral in 1889 no one knows the connection between George and Henry. Speculation is they were brothers.
