Is this him? Only 2 records I found on Ancestry are public records

At ancestry.com there is a tree for a Jeff Hume, born ca. 1873, died early 1895 in Travis Co., TX, at age 22. The only source is a letter written to Richard's mother-in-law Eliza Blackwell informing her of her son-in-law's death; this letter (apparently in family possession) is in the Gallery.
Is this the Jeff Hume you are asking about?
