In 1904 the probate records of Clarissa Bradt, (daughter of John & Martha Rodman of Newburgh) identify several nephews & a niece as follows: Alice (Williams), Charles (dec’d), James & Mandeville COSMAN. Neither of her two living sisters Susan A. Jennings and Sarah Jane Spier who both appear in numerous census records are ever married to a Cosman. Census records for Newburgh between 1860 & 1880 name Arba Cosman as the father of Alice, Charles, James and Mandeville Cosman and in 1860 & 1870 Arba’s wife is given as SARAH while in 1880 he is a widower. In 1850 “Arby” Cosman is enumerated right next door to John & Martha Rodman’s family where he is a widower with a three year old daughter Elizabeth who doesn’t appear again. “Sarah” is obviously married to someone else at this time as she certainly is not in her father’s house next door. With almost the same given name as her sister “Sarah Jane” Sarah must be a half-sister - but who is her parent John or Martha Rodman? And who is Arba’s first wife? And who then is the first spouse of either John or Martha Rodman?
