Notes for John McClain
Attribution of this John McClain as a son of Charles McClain and Elizabeth Moon of North and South Carolina is taken from online family trees at Ancestry.com. I have not verified it against any primary sources, and do not know what the original evidence was, so it may be incorrect.
In 1870 he is listed with his daughter Sarah and her husband William Staton as age 77, wheel wright, born in Kentucky.
In 1880 he is listed with them as John McClane, age 88, border, wheelrite, born S.C. S.C. Vct. (I do not know how to interpret the Vct, but it is entered for several other parent birthplace fields on the page. I suspect it of being an abbreviation for unstated, in some form.)
