I'm hoping to find parents or siblings of Sarah Alder, born in 1816 in Ohio, married 20 Jan 1839 in Fayette Co., Ohio to Robert Colborn. There were three other Alders married in Fayette Co. 1829-1840: Amelia to Levi Briant/Bryant in 1829, Thomas to Tabitha Henkle in 1834, and James to Elizabeth Hoppis in 1838. I do not know if they are related to Sarah or not. And I could find NO Alders in the 1830 or 1840 census for Fayette Co., Ohio. After their marriage, Sarah and Robert lived in Blenheim, Ontario, Canada until 1849 when they moved to Sauk Co., Wisconsin. Any help appreciated.
