We may be a bit off line here. If so, I'm sure Lloyd can correct matters satisfactorily.
My notes show D. W. Hollis, age 22, and Darrell Hollis, age 36, enlisted in Company "H". Almost certainly D. W. Hollis is the Daniel William Hollis noted on the 1907 veterans census. He also appears on the 1860 census of Marion County as Daniel Hollis, age 18, page 584. Darrell Hollis may be found on the same census as Darlen(?) Hollis Jr., age 30, page 609.
Please let me know if something about this isn't right.
