Shilo is a streamlined spelling of Shiloh, the biblical town where the Ark of the Covenant was kept before Jerusalem; the Hebrew name is of uncertain meaning, usually explained as "tranquil" or "he whose it is", after a disputed verse in Genesis. In America the name also recalls the Civil War battle of Shiloh in 1862. Shilo ranked number 6620 in 2015 and has shot up to number 1343 in 2025, its best rank so far.
