Name spelling is always questionable.According to Alderman's in America, Rosina Alderman b. 1764 d. 26OCT 1843 was the daughter of Elnathan Alderman.She married Joseph Alderman, III (b. 1758) 21JAN1782. They were first cousins.Joseph and Rosina had a daughter Rosina b. 1783.Elnathan Alderman b. 1734 d. 1805 m. Lucretia (unknown last name.) AIA also states that Joseph Alderman, III was born in Granby, CT, but moved to Windsor, OH about 1804.I would be happy to copy these pages if you would like them.Hope this helps.
