I am researching 2 Smith families. One on my husband's side and I'm only back to Jacob Smith, born 25 Dec 1810, Virginia, and died 23 March 1878 in Walnut township, Bates county, Missouri. He is my husband 2nd great grandfather.
My 3rd great grandfather, Reuben Smith, was born 1790, Virginia and died Feb 1850, Polk county, Missouri. At one time Reuben was in Tennessee. Sorry I can't help you more.
I will read more about the SW Optical College this weekend and see if I see my great grandfather's name anywhere. We did find his copy of his license. He practiced in Joplin, Jasper county, Missouri for many years until his death in 1941.
