Round-up of multiples from 1944

Badgett quadruplets, born Galveston, Texas, in 1939
Jeraldine, Joan, Jean, and Janet Badgett

Oodles of multiples — eight sets of twins, one set of triplets, six sets of quadruplets, and one set of quintuplets — were featured in an early 1944 issue of LIFE magazine. Most of these multiples had been born in the 1920s and 1930s.

Curious about the names? I knew you would be! Here they are, along with ages and other details.

Twins:

  • Marjorie and Mary Vaughan, 19.
  • Lois and Lucille Barnes, 21.
  • Betty and Lenore Wade, early 20s.
  • Robert “Bobby” and William “Billy” Mauch, 22.
    • They had starred in the 1937 movie The Prince and the Pauper.
  • Blaine and Wayne Rideout, 27.
    • They had been track stars at the University of North Texas in the late 1930s along with another set of twins, Elmer and Delmer Brown.
  • Charles and Horace Hildreth, 41.
    • Horace was elected Governor of Maine later the same year.
  • Ivan and Malvin Albright, 47.
  • Auguste and Jean Piccard, 60.
    • “Honors as the world’s most distinguished pair of twins must go to Jean and Auguste Piccard, stratosphere balloonists, who are so identical that not everyone realizes there are two of them.”

Triplets:

  • Diane Carol, Elizabeth Ann, and Karen Lynn Quist, 11 months.

Quadruplets:

  • Claire (boy), Cleo (boy), Clayton (boy), and Connie (girl) Brown, 3.
  • Janet, Jean, Jeraldine, and Joan Badgett, 5.
    • “The customary alliteration in multiple names accounts for the “J” in Jeraldine.”
  • Felix (boy), Ferdinand (boy), Frances (girl), and Frank (boy) Kasper, 7.
  • James (boy), Jay (boy), Jean (girl), and Joan (girl) Schense, 13.
  • Edna, Wilma, Sarah, and Helen Morlok — the Morlok Quads — 13.
  • Anthony, Bernard, Carl, and Donald Perricone, 14.
    • “Their Beaumont neighbors call them “A,” “B,” “C” and “D” for short.”

Quintuplets:

  • Annette, Cecile, Emilie, Marie, and Yvonne Dionne — the Dionne Quints — 9.

Popular boy names: Biblical vs. Non-Biblical

How has the ratio of Biblical names to non-Biblical names changed over time (if at all) among the most popular baby names in the U.S.?

This question popped into my head recently, so I thought I’d take a look at the data. We’ll do boy names today and girl names tomorrow.

First, let’s set some parameters. For these posts, “Biblical” names are personal names (belonging to either humans or archangels) mentioned in the Bible, plus all derivatives of these names, plus any other name with a specifically Biblical origin (e.g., Jordan, Sharon, Genesis). The “most popular” names are the top 20, and “over time” is the span of a century.

For boy names, the ratio of Biblical names to non-Biblical names has basically flipped over the last 100 years. Here’s a visual — Biblical names are in the yellow cells, non-Biblical names are in the green cells, and a borderline name (which I counted as non-Biblical) is in the orange cell:

Popular boy names: Biblical vs. non-Biblical.
Popular boy names over time: Biblical (yellow) vs. non-Biblical. Click to enlarge.
  • Biblical names: Adam, Alexander, Andrew, Austin (via Augustus), Benjamin, Daniel, David, Elijah, Ethan, Jack (via John), Jackson (via John), Jacob, James, Jason, John, Jonathan, Joseph, Joshua, Justin (via Justus), Lucas, Mark, Matthew, Michael, Nathan, Nicholas, Noah, Paul, Stephen, Steven, Thomas, Timothy, Zachary
  • Non-Biblical names: Aiden, Albert, Anthony, Arthur, Billy, Brandon, Brian, Charles, Christopher, Dennis, Donald, Dylan, Edward, Eric, Frank, Gary, George, Harold, Harry, Henry, Jayden, Jeffrey, Kenneth, Kevin, Larry, Liam, Logan, Louis, Mason, Raymond, Richard, Robert, Ronald, Ryan, Scott, Tyler, Walter, William
  • Borderline name: Jerry (can be based on the Biblical name Jeremy/Jeremiah or on the non-Biblical names Jerome, Gerald, Gerard)

It felt strange putting an overtly Christian name like Christopher in the non-Biblical category, but it doesn’t appear anywhere in the Bible, so…that’s where it goes.

Here are the year-by-year tallies:

200419% of baby boys14 (70%)6 (30%)
201414% of baby boys14 (70%)6 (30%)

But there’s a huge difference between sample sizes of 40% and 14%, so let’s also take a look at the 2014 top 100, which covers 42% of male births.

By my count, last year’s top 100 boy names were half Biblical, half non-Biblical:

Biblical names (49)Non-Biblical names (51)
Noah, Jacob, Ethan, Michael, Alexander, James, Daniel, Elijah, Benjamin, Matthew, Jackson (via John), David, Lucas, Joseph, Andrew, Samuel, Gabriel, Joshua, John, Luke, Isaac, Caleb, Nathan, Jack (via John), Jonathan, Levi, Jaxon (via John), Julian (via Julius), Isaiah, Eli, Aaron, Thomas, Jordan, Jeremiah, Nicholas, Evan, Josiah, Austin (via Augustus), Jace (via Jason), Jason, Jose, Ian, Adam, Zachary, Jaxson (via John), Asher, Nathaniel, Justin (via Justus), JuanLiam, Mason, William, Logan, Aiden, Jayden, Anthony, Carter, Dylan, Christopher, Oliver, Henry, Sebastian, Owen, Ryan, Wyatt, Hunter, Christian, Landon, Charles, Connor, Cameron, Adrian, Gavin, Robert, Brayden, Grayson, Colton, Angel, Dominic, Kevin, Brandon, Tyler, Parker, Ayden, Chase, Hudson, Nolan, Easton, Blake, Cooper, Lincoln, Xavier, Bentley, Kayden, Carson, Brody, Ryder, Leo, Luis, Camden

(Christian, Angel, Xavier, Dominic…all technically non-Biblical, despite having strong ties to Christianity.)

50%-50% isn’t quite as extreme as 70%-30%, but it’s still noticeably more Biblical than 1914’s 25%-75%.

Do any of these results surprise you?
