Was it more common to have two middle names or one?

Hey everyone!

In the late 1800s to early 1900s, was it more common to have two middle names or one?

β€œIn less than a single century middle names were transformed from a somewhat faddish rarity to a practical requirement. The practice did not really catch on with the middle class until after the turn of the century, and became increasingly common within a generation or two. Although only a small percentage of children born around 1800 were given a middle name, it had become nearly customary by the time of the Civil War. By 1900 nearly every child born had a middle name. In fact, the enlistment form used in World War I was the first government form to provide space to write a middle name – a reflection of the assumption that nearly every man had one.”
