I have this book because my aunt, Doris Melugin O'Bryant contributed a lot to it.
Your ancestor, James Henry, is listed on page 98. He is the son of Robert Henry, the son of Henry I., son of William, son of John. All this shows of James Henry is birth year 1888.
Here is the paragraph on Robert Henry's family:
Robert Henry (4) Melugin (Henry I. (3)), born 27 October 1845, Tipton County Tennessee. In his youth he was a Confederate soldier. Private Co. I, 7th Tennessee Cavalry commanded by Colonel W.L. Duckworth. He appears on a Roll of prisoners of war surrendered at Citronelle, Alabama and paroled at Gainsville, May 1865. (Confederate Records, National Archives.) Married 24 November 1872 at Arkadelphia, Arkansas to Mary Chilotte Tarver, born 23 December 1850. Robert Henry died 1916. They are buried at Richland Cemetery, five miles west of Arkadelphia.

(Family records of Thomas Enoch Melugin.)
[* means there is more about this person in the book.)
If you'd like more, I'd be happy to make some photocopies and mail them to you. This will help repay the many kindnesses I've received from other genealogists.
Oh, yes, I'd like to know if you have a family story about how the original Melugin got to this country. Ours is slightly different from the one Margaret related, which is also from Douthitt's book. I think if we hear enough of these, we can glean the kernel of truth from them.
