Jeremy,
Man, nothing will get me to Baseball Reference web site faster than T210's !!!!! 
 
Van Landingham surely looks to be the same fellow (although spelled Vallandingham):

Redfearn is most likely the same guy, although listed with 1909 Charleston/Knoxville of SAL.  1910 in Greenville.  There is also a Redfern of no known first name with Augusta in 1911 (I "assume" same guy).  So why the Columbia team ??  Don't know, just a T210 mistake, or the fact that the 1909 Charleston/Knoxville team of SAL basically folded, and played out the season on the road (sometimes referred as the SAL Orphans).

Either way (or anyway), it's pretty cool, they have Baseball cards !!!!!!
