The other two members of the group were Cassandra Wooten (Cas) and Cheryl Mason-Jacks (see Cheryl Mason Jacks) (jac) from the original The Ritchie Family line up.

In the 2000s, original members Wooten and Mason-Jacks set about reforming the group. Original member Gwen Oliver wasn’t available to be part of the venture so another member was needed. In a 2019 interview with An interview with Lenny Fontana on his True House Stories Show, Cheryl Mason-Jacks (now known as Cheryl Mason-Dorman) said that in the early stages of reformation, Michelle Simpson had been part of the venture and had worked with them for a while. After a stop and a re-start, they settled with Renee Guillory-Wearing.
