I am including a link to the genealogy and local history collection at the Plano Public Library. Their collection includes a photo of Letitia (Forman) Barnett. She was the wife of George W. Barnett (1819-1882). There was also a picture of the Forman home.
The collection also includes a picture of the R.W. Carpenter home, father-in-law of Ruth Donna Barnett, and the diary of Lizzie (Matthews) Carpenter.
