Day As An African American Last Name

The 2010 U.S. Census recorded 105,091 black Americans with Day as their last name. That represented 10% of the total of 10,971 entries.

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

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.

2,418 people named Day were recorded in the 1870 census as black and 526 as mixed.

There was a total of 27,674 people with the name.

Day 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 4,340 people with the last name Day as black within a total of 43,313 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 5,360 people named Day as black within a total of 62,374.

Historic Black Figures With The Day Surname

Here are some notable African Americans in history with Day as their last name.

Lucy Stanton Day

Lucy Stanton’s stepfather was an abolitionist who ran a safe house on the Underground Railroad in Cleveland. Lucy graduated with a degree in literature from Oberlin College in 1849.

She became a school principal and married William Day, a civil rights activist who eventually left her and their child.

After the introduction of the Fugitive Slave Act in 1850, American slave catches started going over the Canadian border to grab escaped slaves. The Chatham Vigilance Committee was founded in Ontario, one of several groups that sought to protect fugitives.

Lucy was a member of the Chatham Committee. Their activities included storming a train in Chatham to rescue a boy, Sylvanus Demarest, being transported to Michigan by a slave catcher.
