>>> The Army of Northern Virginia tumulus, which bears a statue of General Thomas Jonathan “Stonewall” Jackson on a 38-foot high column, has 57 crypts and was established in 1881. Confederate President Jefferson Davis was temporarily interred here. <<<

If he was a member of the Army of Northern Virginia Confederate veterans organization, perhaps he was entombed there. From this internet posting, it appears this tomb was in use as early as 1881.
