In 1998 there were 6919 triplets and 627 quadruplets born in the United States. There were 79 quintuplets or higher births in the U.S. Just a little more than three decades earlier, author Amram Scheinfeld, in the book 'Twins and Supertwins', estimated that there were probably no more than 250 to 300 surviving sets of triplets annually among the U.S.'s four million births and there were only 10,000 sets total triplets of any age throughout the U.S.
Until 1967, the United States had never averaged one living set of quadruplets per year and estimates made in 1972 in the book 'The Curious World of Twins' theorized that perhaps only a dozen living sets of quadruplets were in the U.S. The numbers had increased slightly a decade later as supertwin statistician Helen Kirk Lauve estimated there were 101 complete sets of quads and eight sets of quints living in the U.S. in 1981.

Two major reasons (in-vitro fertilization treatments, women giving birth at older ages) for this amazing increase in the birth of multiples across the world are well known. But lesser known are some of the early pioneers in multiple births, the pre-fertilization treatment quadruplets, quintuplets and sextuplets.

Quadruplets

Obviously, the birth of pre fertility-drug quadruplets was quite a rare event. Perhaps even more rare was the birth of identical quads. Two of the earliest examples of identical quadruplets in the United States were the Morlok girls (Edna, Wilma, Sarah, and Helen), born on May 19, 1930 in Lansing, Michigan and the Hargreave girls born in 1949. The Morlok's turned 71 in 2001 and were the oldest-living quads in the world until one of the sisters passed away before what would have been their 72nd birthday.

The Keys Quadruplets were four girls born in Hollis, Oklahoma on June 4, 1915 and all four girls (two identical, two fraternal) ended up going to Baylor University in Waco, Texas, where they graduated together in 1937. About 60 years later, another set of quadruplet girls, the identical Hansen Sisters, would also go on to matriculate at Baylor.

Other early quadruplets in the United States were the Schenseses of Hecla, South Dakota (two girls and two boys born on January 13, 1931), and the Perricone boys of Texas in 1929 (the first all-male quads in the U.S.) and the Fultz girls of North Carolina (1947), the first black set of quads in the United States who were also likely the second set of identical quadruplets born. The Fultz Quads, Mary Alice, Mary Louise, Mary Anne and Mary Catherine, are shown in a 1962 UPI photo (l to r) below meeting President John F. Kennedy. The Perricone Quadruplets petitioned the U.S. Army successfully so that all four could serve together in the Korean War.
Quadruplets can arise in the same way that twins form, either from
fertilization of four eggs or one embryo splitting twice. Obviously to
have four ova present at one time is particularly rare and the most common
cause of quads is a double split. Of course it is also possible for 3 ova
to be fertilized and then one splits to give a total of 4, giving two
identical and 2 non-identical babies; but again this would be quite rare.
It is not fully understood why an embryo splits but it occurs when the
casing of the embryo (the Zona Pellucida) splits with the first cellular
(bastomere) split. Normally these blastomeres split repeatedly within the
confines of the zona to form one individual. It is really an intact zona
pellucida which denotes a singular embryo. Eventually the cells fill the
zona so much that it hatches and releases the blastocyst. At this point
the cells are so organized (differentiated) that only one fetus can arise
from them.

Hi, Deyanza...

There's actually a good book on multiples by Dr. Barbara Luke and Tamara Eberlein called "When You're Expecting Twins, Triplets, or Quads" that might come in very handy for you. Like other multiples, quads can be either Identical or Fraternal, though Identical is much more rare when there are more than three babies.

It is utterly viable that I'll have quads someday, as multiples are familiar in my loved ones, and I've suggestion approximately names if that have been to occur. For a few unknown rationale, I'm satisfied it could be three boys and one million woman if I did have quads. If that have been the case I'd identify them: Braeden Michael Kieran Josiah Declan Isaiah Laken Reese
