I believe Dewitt, George P. and William J. Hollenbeck were brothers. 1870 census in Cortland with parents Frederick and Mary. William died 1901 in Cortland and Dewitt 1924 in nearby Dryden, Tompkins County. Looking for a "Sarah Eliza" born c. 1832 who may have been an aunt, ie. Frederick or Mary's sister?? Any information appreciated, especially on Dewitt's descendants. Thank you.
