Since my posting I have been able to connect with my family.
As you pointed out: THADDEUS ARKANSAS(Warsaw?)SMITH, son of LOVET SMITH and MOURNING ?, married on 12/19/1880, in Levy County, FL, VICTORIA EUGENIA WILKINSON, daughter of JAMES HENRY WILKINSON,Sr and MARY AMANDA HIGHSMITH. These are my G-G-Grandparents. As you see, Victoria's mother was a HIGHSMITH.
This all came as a surprise, in that my mother was also a HIGHSMITH, which means that I am related to the same family tree on both sides of my family. *This may explain a lot* Guess this family tree doesn't have a lot of branches.
I don't beleive that I am related to the AARON SMITH that you mentioned, at all.
