I looked up the trees on ancestry.com and found Lorenzo listed under William arch Falin and Loura Kitts and Williams parents were Martin Falin and Julia ann Campbell. However, I looked on the 1900 census on ancestry and could not find him listed on there under any William ARch Falin.
under any spelling, he had a sister named Minnie but could not find her under there either. William later moved to McMinn co. Tn and died there in 1949. Sorry I could not find more to help.
