Antonio's Notebook details how children became members of the clan. If they had a great affinity for Spirit Energy (a connection with magic), then they could become Witches and children could be born either within or outside of the clan. The children would take part in drills with the older Witches and would eventually take the 'Witchly Vows' as they became women. So the chances would be, yes, there were other children within the clan such as Bayonetta. Jeanne even confirms as much when she says they used to play together during their childhood.

As for Bayonetta's power, she is again a special case in terms of what she can do. As a child of both a Lumen and Umbra, she has incredible connections to magical power and can use those to the extent that most other Witches could not because of it. Her status as the Left Eye only increases her strength, but not to the extent that she could possible attain (Loptr states that she isn't reaching the full limit of her power despite posessing the Eye in Bayonetta 2).
