list that wraps around and keeps position

on one sheet i have a list of names (for this example let's visualize the alphabet as the names)

on another sheet, if i type in A on the first line

a list from A to Z will populate from top to bottom

if i type in L on the first line

a list from L to Z will populate & after Z will come A - K then the list will stop

post script: i have names of employees that have a particular order.

every other day a diff person will be first, and the order must be kept and wrapped around back to the top person.

not sure how to do this... appreciation for all replies
