Company records list Susan's husband, Silas Horace Tracy, as head of household with a traveling group which consisted of three adults and one child. It is assumed that she and her son were among that number. Further research is needed to determine who the third adult was traveling with his family. However, based on census data in 1860, and later family recollections, it appears that Susan Almira's mother, Elizabeth Voorhees, was the unnamed adult that traveled with them.
