Descendants of my Adsit line went to Grant Co Indiana also.Mary Ann Adsit, my direct line died in Delaware Co Indiana. One of her brothers had a son Ranselar Adsit.My Adsit genealogy lists only one child for Ranselar Richard b. 1833 which I figure is about the right time for your Harriet. I thought this might me a hint for you. I have no idea if he lived in Grant Co Indiana. He married a Margaret Thompson.I have no dates for either of them.
