Re: Charles Eisentrout 1831-1932 Germany>MD
I just found on the 1900 Allegany County, MD census an Elmer, born September 1887 living with his grandparents, Charles and Mary Iesantrout on Linden St., Frostburg. It says his father was born in Wales and mother in Maryland. There are two daughters also in the house, Henrietta, age 39, and Rebecca, age 31, both single. There also are sons Rex, Joseph and Thomas. Do you think this could be your gr-grandfather? If so, I'd love to share more.
I have found the same Charles with his name spelled Isentrout on the 1880 census, Eisentrout on some Civil War payroll things online, and Iesantrout on his headstone. His sons Rex, Joseph, and Charles Henry's death certificates all have the spelling Eisentrout.
