The Branch family of Indiana

Indiana politician Emmett Forest Branch (1874-1932)
Emmett Forest Branch

A century and a half ago, Elliott and Alice Branch of Martinsville, Indiana, welcomed four babies, two girls and two boys:

  • Olive L. Branch (b. 1869)
  • Leafy Dell Branch (b. 1871)
  • Emmett Forest Branch (b. 1874)
  • Frank Oak Branch (b. 1878)

According to a newspaper article from 1903, the Branch family was “one of the oldest and best” in Indiana’s Morgan County, but “the names of the children of this branch of Branches the oddest.”

Their mother, who was of a poetic turn, was responsible for the names, Forest, Oak, Leafy Dell and Olive.

Emmett Forest Branch went on to spend three terms in the Indiana House of Representatives (during the first decade of the 1900s) and serve briefly as the governor of Indiana (from April of 1924 to January of 1925).

P.S. Speaking of “olive branch,” did you know that the maternal grandfather of Supreme Court justice Thurgood Marshall was named Isaiah Olive Branch Williams?

Popular baby names in Colorado, 1997

Flag of Colorado
Flag of Colorado

Back in 1997, the western U.S. state of Colorado welcomed 56,505 babies.

What were the most popular names among these babies? Hannah and Jacob, according to data from the Health Statistics Section of Colorado’s Department of Public Health and Environment.

The state also revealed the top names within each of its three largest racial/ethnic groups, which it defined as “White/non-Hispanic,” “White/Hispanic,” and “Black.”

Number of babiesTop girl nameTop boy name

Here are Colorado’s top 50 girl names (overall) and top 50 boy names (overall) of 1997:

How do these rankings stack up against the U.S. Social Security Administration’s 1997 rankings for Colorado?

The boy names look similar, but there are two significant discrepancies among the girl names: Alexandra ranked 11 spots lower (19th vs. 8th) and Gabrielle ranked 33 spots lower (75th vs. 42nd) on the federal government’s list.

Other names bestowed in Colorado in 1997 included “Elway, Jamaica, and Mars for baby boys, and October, November, Paradise, and Rejoice for baby girls.”

Elway was no doubt inspired by John Elway, the longtime Denver Broncos quarterback who was about to lead the team to its first Super Bowl victory (in January of 1998).

Speaking of Colorado baby names with historical significance…here are posts about Denver (b. 1859), Colorado (b. 1859), Salida (b. 1881), and Silver Dollar (b. 1889).

Did you know that you can find old vital statistics reports for the City of Philadelphia on the city’s website? And that most of these reports include baby name rankings?

I don’t want you to have to comb through a bunch of PDFs to find Philly’s historical top-ten lists, though, so — just as with New York City and Austin — I gathered all of them into a single blog post.

I was able to track down eleven sets of rankings — six covering 2005 to 2010, five covering 2012 to 2016. Eight of them also happen to include total numbers of babies.

Finally, because Philadelphia and New York City are relatively close to one another, I thought I’d compare/contrast the rankings above with the NYC rankings for the same years (2005 to 2016, excluding 2011).

Parents in both cities often liked the same names, but not always at the same time, or to the same degree. During the years that Kayla ranked #1 in Philly, for instance, it was already on the decline in NYC.

Here are all the names that reached the top 10 at least twice in one city, but zero times in the other city:

Girl namesBoy names
Top-10 in Philly only
(2+ instances)		Aubrey, Destiny, Gianna, Layla, London, Makayla, Nevaeh, SkylarElijah, Isaiah, James, Mason, William
Top-10 in NYC only
(2+ instances)		Ashley, Chloe, Leah, Sarah, RachelDylan, Justin

Any thoughts on these differences?
