A $10 photo from an antique store in Tucson. On the back written in black pen is "Alex Masters family." The studio mark on the front is Oswald's Extra Finish 1227 W. Washington Ave N. Minneapolis. Alex Masters' family. The family is posed in front of a house. A man, probable wife, and seven children. The clothing suggested an 1880 to 1910 time frame. I started by searching the 1900 census for Alex* Masters in Minneapolis, then Hennepin County, then Minnesota. Nothing found. Same for 1910 census. I then searched all US censuses. Nothing found. I broadened search including newspapers. Nothing found. They remain mystery.
