Hi, Janet Saw your posting....I came across this while looking form my Alexanders in the Tennessee area.It mentions a J.L. Alexander, maybe the one you speak of?
G. D. Alexander, merchant, was born in Smith County, in June, 1849, and is one of nine children of J. L. and Sarah D. [ Donaho] Alexander. The father, Scotch in origin, born in Smith County in 1818, has been a physician near Dixon Springs for forty-six years, and is also a farmer, possessing about 500 acres of the Cumberland River bottom lands, one of the finest farms in the county. The mother, French in ancestry, was born in Sumner [now Trousdale] County in 1829. Educated chiefly at Dixon Springs, our subject began merchandising at nineteen years of age in Smith County, continuing about three and a half years. For five years then he was employed by Jos. T. Thompkins & Co., dry goods, Louisville, Ky., and then before engaging in his present business at Dixon Springs, he spent four years on his father's farm. In December, 1885, he married Bettie, daughter of Jas. and Clarissa [Bravard] Crenshaw, and born in what is now Trousdale County, in 1863. Mr. Alexander is a Democrat, and his wife is a member of the Christian Church. http://www.rootsweb.ancestry.com/~tnsmith/tngen/goodspeedsmithbio.htmhttp://www.rootsweb.ancestry.com/~tnsmith/tngen/goodspeedsmithbio.htm
