I purchased the subject studio portrait of two young women taken byNast, Denver, CO.It is identified on the back of the mount:
"Bertha & Maggie Olson Littleton, Colo daughters of Aunt Mary Olson Aunt Mary is sister of M H Judd. Taken about 1901 or '02"
These individuals appear in Public Member Trees posted on ancestry.com.The correct spelling of the surname is Olsen.They are listed in the 1900 Census data for La Jara, Conejos Co., Colorado; and the 1920 Census data for Precinct 12 (resided on Platte Canon Road), Arapahoe Co., CO.Maggie was enumerated twice in the latter census; she is also listed in the 1920 census data for Washington, DC (resided on 21st Street).Bertha is also listed in the 1930 Census datafor Precinct 12, S.W. Littleton, Arapahoe Co., CO.
Bertha Ellen Olsen, born 14 Nov 1882 in CO, died 1960, and Maggie Regina Olsen, born 27 Jul 1885 in MN, died 5 Dec 1955, were daughters of a farmer, John S. Olsen, born 5 Jul 1846 in Hedemarken, Norway (immigrated 1869), and Mary Ann Magnes, born Apr 1862 in CO, died 1934.Apparently, neither daughter married.In 1920, Maggie was employed as a clerk for the federal government (Treasury).
