I am looking for any information on John Henniger and Magdeline Hornberger, who came to Austin Texas around 1853 and had a house & farm @ 3rd and Congress. The house and surrounding farm would later be transformed into the I & G N RR Depot in Austin. They had a daughter, Katherine, or Kate, my Great,Great Grandmother, who married George Kuempel. They then resided in a home at 17th and Congress from c. 1875 until c. 1890. They then moved to the Pflugerville area. Any info would be greatly appreciated.
