Update adds children to this Guillaume & Ermengarde. (See Overview) Four new children may be added to the parents:
1. Étienne
2. Robert II (d. ca. [1096])
3. Guillaume (d. bef. [1059/1066])
4. Begon (d. after 1044)
5. Ponce (d. before [1059/1066])
After searching, I found no primary or secondary source that supports Beliarde Philippa d'Auvergne as another child.
