Sabrina,Is there any chance that your first name is an old family name?The reason I asked is that I was research a Silas Beverly on the 1860 census....I think his mother's name was Sabrina.
Anyway, living in the house with him were seven Colson children.No father or motherlisted. There was a Sabrina, age 13.She would have been born about 1847.The other seven were all males. J. J. Colson, 22, Collin Colson, 18, David, 16 Sabrina, 13 Silas,11 Nobel V. 8 Robert H. 5
This might be a place to start looking to see if one of the men passed the sister's name down.It wasn't a common name in that area in 1860.
