Commentary
Liegard's father is shown as Heribert in the Flodoard, Annales.

Weis: Line 121E-19 claims she was killed in 942 as the 2nd wife of William Longsword, but in Line 136-19 claims she married Theobald of Blois, the slayer of her husband, in 943, and did not die until sometime after Theobald, who died in 978.
