Hi Lauren, I will have to sort through some papers, but I had a census that showed an Elizabeth Aldridge living with Otha and family. The year may have been 1850? By that time they were living in Ogle Co. IL. This census listed an Almira as the oldest child but there was not an Emma listed. I believe that the Elizabeth may have been Susan's mother, (by her age.) Maybe Elizabeth had married again to someone whose last name was Aldridge and he had died too. Thanks, Brenda
