Sylvia Ross was born in Aurora, Il August 26, 1935. If living she would be 71 yrs of age. Her Mother's maiden name was Sylvia Seibenthal AKA Sylvia Tell - First American Premiere Danseuse - born November 19, 1903 in Milwaukee, Wisc. The last information I have is they resided in Las Vegas, Nevada in Dec. 1940. Sylvia Seibenthal Ross's mother was Marguerite K.Tell Seibenthal and lived on a farm in Aurora in 1934. Becuse daughter and mother have the same name it becomes a bit confusing.....but the mother began using the name Sylvia Tell, after her mother's maiden name for professional reasons as well as a divorce from Wellington E. Ross Jr. AKA Dick Ross. If anyone one can shed any light on their movements after 1940 it would be greatly appreciated.
