It does; it has the same type of name stamp we see on Cross photos and he's on that Stilwell list you posted (many of which are Cross images, though they seem to draw on photos from a 15 year + time span):
Cross was born in Vermont in 1839. His older brother, Daniel H. Cross - a former Union Army photographer - taught him photography. In 1867 he married and moved to Omaha, Nebraska. He was one of the first professional photographers to live on the edge of the Great Plains.
From July 1878 Cross spent the next twelve years in Niobrara, Nebraska. Cross photographed Native Americas and belonged to a circle of photographers that satisfied the demand for photographs of Native Americans. From the late 1870s to 1890s he traveled the Reservations in the Dakotas and took hundreds of photographs of native celebrities. He shot series at Fort Randall (Sitting Bull and the Hunkpapa POW), at the Rosebud Reservation (Spotted Tail Agency), at Pine Ridge (Red Cloud Agency) and in surrounding areas.
It is known, that Cross and his family left Creighton in February 1878 for the Spotted Tail Agency. They remained for about 4 months and Cross photographed members of the Brule band and scenes of the agency. Like other photographers Cross was a businessman. These frontier photographers generally operated a studios in their home towns, but traveled with a tent gallery all over the country. Like other photographers he often placed announcements in the newspaper, informing local townspeople when he would be in their vicinity to offer his services. It is known that Cross also distributed his photographs through other entrepreneurs. E.g. Bailey, Dix and Mead marketed the well-known "Sitting Bull PoW" series and L.W. Stilwell photographs with Pine Ridge themes.
In 1886 Cross met in the Niobrara-Valentine area his apprentice John A. Anderson, who became a known photographer in his own right. In 1888 Cross and Anderson moved to Fort Meade near the Black Hills, but stayed only for some months. Later Cross acquired a gallery from a J.W. Pike in Hot Springs, where he lived in proximity to the Pine Ridge Indian Reservation. Around the middle of January 1891 Cross traveled to Pine Ridge where he stayed until the end of the month. His aim was to take photographs of the Wounded Knee masscre site. It is known, that he photographed some military units that still occupied the reservation and some scout units.
At the age of sixty-eight Cross died of pneumonia on December 23, 1907. Cross was survived by his wife Jennie, a son named George, and three daughters, Florence, Cleva and Mrs. L. G. Miller. According to different catalogues about 500 to 600 photographs of Cross are known.
