Blackwell As An African American Last Name

The 2010 U.S. Census recorded 13,426 black Americans with Blackwell as their last name. That represented 28% of the total of 47,175 entries.

This article tracks their numbers in the census since the Civil War. We also look at historic African American people named Blackwell.

We end with a review of early records of black military service in the United States.

After The Civil War

The 1870 census was the first survey after the Civil War and the Emancipation Proclamation. In 1850 and 1860, only free African Americans were recorded in the census. The many enslaved were omitted.

From 1870 onward, all black Americans were included.

2,001 people named Blackwell were recorded in the 1870 census as black and 246 as mixed.

There was a total of 7,331 people with the name.

Blackwell In The 1900 And 1940 Census

The mixed category was dropped from the census in 1900, so we just need to look at the black numbers this time.

The 1900 census recorded 4,052 people with the last name Blackwell as black within a total of 13,521 that year.

By the way, the mixed category returned in the 1910 and 1920 censuses. It was dropped again in 1930, but replaced with extra categories for colored and non-white in a way that seems confusing now.

This changed again in 1940 and we can simply focus on one black category.

The 1940 census recorded 5,195 people named Blackwell as black within a total of 24,221.
