Research Notes

On family genealogies prior to 1582 he has a morganatic marriage with Anna Van Aldekerk (1565-1616) and a son with her Herman Isaac Op den Graeff who is classed as illegitimate as the son could not inherit the titles or privileges due to the morganatic marriage.

However there are no primary/original sources for either the marriage or that he is a father of a son, and it is most probably a mistaken reading of a source and is definitely unproven.

Removing Anna Van Aldekerk (1565 - 1616) (https://www.wikitree.com/wiki/Van_Aldekerk-1) as his wife. They may have had a morganatic marriage but there are no sources for that. And this relationship keeps showing up in my connection finder results giving me a less then accurate connections to the WikiTree World Tree. ( Erik Granstrom, Oct. 28th, 2020.)
