I'm a descendant of Theresa Agnes Nordhausen Seeberger and her husband Julius Seeberger through their daughter Elsa Julia Seeberger Price. I don't remember hearing about any land in Humble, as far as I knew she lived in the West End area of Houston on Washington Ave.
Regarding the Bremen connection mentioned in another reply to this item, neither the Seeberger nor the Nordhausen families were from Bremen but Gerhard Nordhausen, father of Theresa sailed from there when he emigrated to Texas in 1855. He was from Astede, Oldenburg.
Heinrich Seeberger, father of Julius, emigrated from Canton Argon, Switzerland via Havre France to New Orleans in 1857.
