Source: {ref:S756@Weis} says about 925 and {ref:S929@Cawley} says about 900, but according to Weis, his parents married in 911, and both sources say he married in 935 and received his title of Count in 934.

Source: Cawley says he was born about 997, but also says that he subscribed to his father's charter in 1002, so a date as later as 997 seems unlikely. To clarify where he got his birthdate from he says, "It is unlikely that Bodon, assuming he was the oldest child by his father's marriage to Mathilde de Mâcon, could have been born before [997], given the estimated birth date of his maternal grandfather. Bouchard raises the possibility that Bodon and Landry were sons of an earlier marriage as "they seem to have had no claim to Nevers". However, it looks likely that they both predeceased their father, and it would have been improbable for [a] surviving infant issue to be installed as count instead of their adult paternal uncle. Bodon succeeded his wife's maternal uncle in [1016/20] as Comte de Vendôme, by right of his wife".

Source: Cawley says between 1025 and 1035, and that her marriage was repudiated in 1048. If we assume she married no later than 1047, then we can assume she was born before about 1032 and probably sooner.

Source: {ref:S905@Cawley} says her parents married before 1066 and that she married before 1080. He also says her grandparents married about 1050/54.
