I also have a great-grandfather named Columbus Allen, married Rachel Evelyn Lloyd.He would have been born abt.1850 give or take. I don't know where he was born, GA. SC. AL. TN.?His daughter Lou (born Sept. 27, 1877) married my grandfather Calep (Caleb) Milton Ford in Calhoun Co., AL.They both were born in Calhoun Co. and are buried in Calhoun Co,AL.My father thought that Columbus's first name was Christopher, but other sources list it as Columbus with middle inital of "H".
