From Wikipedia:
Prior to becoming "The Sylvers", the four eldest members (Olympia, Leon, Charmaine, and James) recorded as the Little Angels, appearing on variety shows such as "Make Room For Daddy" and "You Bet Your Life," and opening for such acts as Johnny Mathis and Ray Charles. Also during this time two singles were released: On the Warwick Label - "Santa Clause Parade b/w I'll Be A Little Angel" and on the Capitol Records Label - "Says You b/w Olympia."
The Sylvers consisted of nine siblings:
Olympia-Ann "Olan" Sylvers (b. October 13, 1951) - Vocals
Leon Frank Sylvers III (b. March 7, 1953) - Bass, Vocals
Charmaine Elaine Sylvers (b. March 9, 1954) - Vocals
James Jonathan Sylvers (b. June 8, 1955) - Keyboards, Vocals
Edmund Theodore Sylvers (b. January 25, 1957, d. March 11, 2004) - Vocals, Percussion
Joseph Richard "Ricky" Sylvers (b. October 13, 1958) - Guitar, Vocals
Angelia Marie "Angie" Sylvers (b. April 11, 1960) - Vocals
Patricia Lynn "Pat" Sylvers (b. March 25, 1961) - Additional Keyboards, Vocals
Foster Emerson Sylvers (b. February 25, 1962) - Additional Bass, Vocals

During 1972 the act was joined by brothers Edmund and Ricky. The sextet changed their name from the Little Angels to the Sylvers and released three albums on the MGM/Pride label, titled simply "The Sylvers," "The Sylvers 2," and "The Sylvers 3." Released between 1972 and 1974, these LPs were comprised of solid soulful numbers written by Leon and produced by R&B legends Jerry Butler (of the Impressions) and Keg Johnson. Four singles from these self-titled albums were popular enough to be recorded on the Billboard R&B charts, starting a sequence of successes for the siblings.

The group are probably best known for their Disco hit "Boogie Fever," but I've always really dug their early 70's soul output. So I thought I'd share a few treats:
The Sylvers:
Come On Give Me A Chance
Foster Sylvers:
(This is awesome cover of the Smokey Robinson and The Miracles hit.)
Enjoy.
