The period follow Juneteenth is known as the "Scatter"

As an understandable response - most freed people after the announcement weren't terribly interested in staying with their past owners, the people who had enslaved them, even if payment was involved. In fact, some freed people were even leaving before Granger had finished making the announcement to show their disappointment and disagreement with the terms of the Juneteenth announcement.

In the following weeks, some freed people listened to the order and stayed, but many did not and escaped their captors as soon as possible. Some knew about the event later but still chose freedom. Stories about the days were told: “When freedom was declared, the master wouldn’t tell them, but mother, she heard him telling mistress that the slaves were free, but they didn’t know it, and he was not going to tell ‘em till he had made another crop or two. When mother heard that, she said she slipped out of the chimney corner and cracked her heels together four times, and shouted, “I’s free, I’s free.” Then she ran to the field, against master’s will, and told all the other slaves, and they quit work.”

Just like that, after the Juneteenth announcement, formerly enslaved people left Texas in great numbers to find family members and make their way to the postbellum United States. That period of time is known as the "Scatter".
