Question

Doesn't seem like a valid entry as birth yr is 5 years after listed father's death.

Answer 1

Agreed, sounds like there is a generation missing in that family.

Doubtful he would have children 30 years apart also.  Maybe Henry was son of Henry, not Thomas.  Births would match better.

Is the Garrett Genealogy online?  Remember all sources that state they are of a surname are not necessarily sourced well. Many are, but there can also be errors in any of them.

Yes, the Garrett geneaology is online and is cited already under Thomas' profile:

Here is the entry from Garrett showing Henry Harrison as Henry Grandison's son (not brother):

19. HENRY HARRISON⁴ LAWRENCE (HENRY GRANDISON³, THOMAS², HENRY¹) was born June 7, 1841 in Graves Co., KY, and died June 28, 1916 in Ozark, Johnson Co., IL. He married (1) MARGARET O'NEAL July 1, 1863 in Johnson Co., IL. He married (2) MARY J MOHLER September 17, 1864 in Johnson Co., IL. She was born August 21, 1842 in North Carolina, and died May 12, 1917 in Johnson Co., IL.

The will for Henry Grandison states that Henry Harrison is his son, so that would be the missing generation.
