The Hamblin account places Sylvia's mother, Martha Mecham, in the Aaron Johnson Company of 1850. It is assumed that Sylvia, who was only an infant at the time, would have been traveling with her.

In some sources her surname is spelled "Meacham". Birth and death dates listed were found in a personal, online family history record (such as Family Tree, Ancestry, or My Heritage), without any accompanying documentation. Further research is needed to verify its accuracy.
