The Owens Migration

The Victoria Advocate, a Texas newspaper in the mid 1800's, had printed a brief announcement for the community of Goliad, Texas and surrounding area.  It was really amazing when you think about moving thirty-nine members of your family at once.  We currently have issues of getting five of us together.  But the announcement created many questions:
1.  Why the devil would you leave Florida for Texas?
2.  Why move an entire family?
3.  Was there a plan?
4. Who traveled?  and How did they travel?

I then found a narrative that stated the Owens family came on the USS Gov. Bennet from Florida (assuming Pensacola) to Indianola (a popular landing for Texas) and then Goliad . All 38 and in a ship.  I also assumed they did not count the slaves on this family emigration.
