Mary Adell Rogers was born in Albany, New York, on October 15, 1849. I haven't found the names of her parents yet.
On July 4, 1865, she married Thomas Salvester Allen in Wisconsin. They had four children while living in Wisconsin. The rest of their children were born after they emigrated to Nebraska.
Mary died February 12, 1910, in Cody, Cherry, Nebraska. Records indicate that she died from complications of diabetes.
