I can't find any good information about them. Landry Comte de Monceaux (son of Bodo) is mentioned at FMG.ac. Death date listed as 1028. It states "He was invested in 990 as Comte de Nevers by his father-in-law as a reward for services." With a birth date of 970, it seems he would just barely be old enough for that to be reasonable. He could have been much older. However, birth dates of 950 and 938 for his father are both reasonable if 970 is correct for Landry.
Therefore, I believe they are the same person.
