You received some wonderful responses, vicky!
Remember to re-view. Did he have relatives in or near Galveston? It would not have been the norm to travel so far 'alone', even to attend the first public school in Texas. Did he board? Where and with whom?
The fact that he was back home by 1900 is not surprising. 1900 was the year of the great 1900 Hurricane, where over 6000 people died.
There were other 'second' schools opened in Galveston from 1886. The Dominicans, Sisters of the the Holy Spirit and the Josephites were active in the area, opening 'free' schools for African-American children.
