Alexander As An African American Last Name

The 2010 U.S. Census recorded 69,653 black Americans with Alexander as their last name. That represented 34% of the total of 204,621 entries.

This article compares census numbers before and after the Civil War. We also look at historic African American people named Alexander in the last three centuries.

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

Alexander Before The Civil War

The 1850 census was the first to record all free members of households together. Before this, people who were not white were not named in the federal census.

In 1850, there was a box to enter color on the census. There were three categories: white, black, and mulatto. The third term is the language of the time, and I will use mixed in this article.

If you are researching your black Alexander ancestors in census archives, be sure to check the two non-white categories. Do not assume that the people recording the information were always correct.

1850 Federal Census

There were 317 people named Alexander who were recorded as black in the 1850 census. 169 were recorded as mixed.

Because they are in the main federal census, we know that they were free citizens.

There was a total of 17,624 free citizens named Alexander that year. There would be one more census in 1860 before the Civil War.

After The Civil War

The 1870 census was the first survey after the Civil War and the Emancipation Proclamation. All African Americans were included.

Those who were omitted in 1850 and 1860 because they were enslaved were now recorded.

8,730 people named Alexander were recorded in the 1870 census as black and 1,486 as mixed.

There was a total of 35,415 people with the name.

Alexander In The 1900 And 1940 Census

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

The 1900 census recorded 17,639 people named Alexander as black within a total of 59,522 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 25,333 people named Alexander as black within a total of 100,756.
