This is a photo of Ada McDowell who graduated from the University of Denver with a bachelor's degree and then a master's. Was supposed to teach business arts in Tillamook, OR school district but don't think that happened. She moved to Chicago and worked for a law firm there until her death around 1981.
This is on a heavy metal piece. I had them digitally redone. I think this is a picture of my Great-great grandfather Louis (Luigi) Mazza with his wife, Luisa, and my great-grandmother Mary (Maria) taken in Italy before they came to the US in about 1877. They came into Vermont but then to NY by 1890.
I have the original of this photo and was told that it was my grandmother's favorite uncle, Robert McDowell. This Robt was born in Brooklyn in 1852 and moved to CO @1886. The crosspiece has the number "84" which is the National Guard unit for Brooklyn. Since this Robert McDowell wasn't old enough to serve in the Civil War, it may be a different McDowell.
